  1. @Nominal mentioned me in Spam the other day, and i had actually been thinking how it was just rusting way, again... About time for an update from @azzurro - probably rusting away again. ___ Its pretty much been sat in this barn since my last post a year ago, except for when the barn was used for a wedding and it got pushed outside - groom was italian and stoked with it, and apparently it was used as a prop and is in some of the wedding photos, lol Its always been a bit of a pig to start when its been sitting for more than a day or two (first pop otherwise) as the fuel pump takes a long time to suck gas up from the tank, and the slightly flat battery wouldn't have lasted. It was also running a bit flat/missy when i put it away. I cranked it for a bit hoping for a miracle, but before i flattened the battery I pulled the carb top off to fill the bowl with gas, but it had a lot of brown sludge in the bowl so took the whole thing off and gave it a quick dismantle on the ute tail gate. Also adjusted the linkage to get full secondary opening, and with some gas in the bowl it fired up pretty much straight away A quick check of the brakes, lights and etc, and swapped spots with the ute, patted the resident donkey, and drove it home no worries at all. Its such a lush cruiser, its supposed to have 85 series tyres so its pulling 3500 rpm in 4th at 100, so while its more than happy there, its nicer to take it easy. However, it sounds great with a hole in the exhaust - the secondary opening fully has also given it a bit more top end howl too, and the small 6 is so smooth. Drive reminded me of a few small things I had on my list that need doing for a WoF - Ill install an electric fuel pump as per the utes set up (i bought two for this reason) - the exhaust needs replacing between the manifold and the rear door - i backed into the rear bumper with my old van and so i need to check out the spare one - check the ignition timing - so far has been done by guessing - there are no timing marks on the engine (they are on the flywheel requiring timing to be set with the engine running on a stand - what the flip), OR, you need a special tool. Well this NOS bad boy turned up on trademe for $15 so i bought it NOW. Looks like a precision tool, but it kinda jams between the water pump and timing chain case, and then the hole in the blue part fits over a bolt and dangles over the crankwheel. More fiddling to follow

    Rust repair - butt vs lap joints

    Good plan. If you draw/ mist some primer round the new panel onto the car and through the hole onto the panel will give you min/max cut lines on both and a better idea how much panel you have to play with/ how much more you could chop out. You could also self tap the panel in (temporarily) and run the cutting disc between the two lines above to make a nice matching seam to butt weld. As long as you have the panels nicely lined up, take your time and some flap discs theres no reason that seam would be visible when its all finished
  3. great work man, as usual love the wee video, each time gaining a wee bit more speed and confidence. engine note is suitably angry, but in kind of a cute way, "ohhhh look at the cute widdle puppy trying to be tough and growly - whos a good boy? you are. yes you are" gggggrrrr

    Rust repair - butt vs lap joints

    IMO you only want butt welds where you joining mid panel to mid panel so its invisible, basically where you are replacing rusty sections with new panel sections. Use lap joints (with plug welds) to replicate the factory spot welds where they would have existed before. Lashings of seam sealer to keep the moisture out of the overlap. As Valiant says, there is a bit of trick to thinking about the order of assembly re getting the grinder or mig torch in especially in the inner corner of the floor - eg maybe butt weld the floor section in, build up the inner sill to the new floor datum, build the outer sill (butt to the fender and sill, plug on the bottom lap) and plug weld the floor lap to the new inner sill last. Also that patch looks pretty rusty - best to cut more out untill you get to good metal, as its easier to make a bigger patch now, than try to weld to rust and then redo the repair in a year when the weld blows out.

    V close, spanish 151 with a '92 casting date and 3 progression holes I set the butterflies on the bench to there and also with a torch on the car a couple times to balance visually but not looked lately now they are balanced Pretty sure low float levels/ excessive angle was/will be messing with my tune, beyond any design flaw, as while theres still a small stutter its nowhere as bad now i gave the inside/lower float a wee tweak
  7. bit more carb tutuing, upped the main jet to 135, better on transition, but maybe too rich on WoT. diddled with the the idle mix, ok, but still a bit funny. Read and reread my various carb books. decided to tweaked the floats, as the carbs are on a 12* angle to horizontal, (max recommended is 5*), the lower or inside side float will tend to cut off the needle valve earlier than it should making the fuel level low, especially in the upper or outside fuel well: ...and as it is written, so it comes to pass... Bent the inside float up a bit, and left the outer as it was (factory 25mm). Average fuel level is probably still a bit low, but too high will be bad too. WAAAAAAAY better now, i think the idle jets were sucking a bit of air every know and again or something, and the progression flat spot is much improved as the ETs have a few more holes covered. Tweaked the timing a bit more advanced as well (12-15* at idle) and the whole thing is now much livelyer. Idle is smoother and i leaned it back to a 'steady' 13.5 AFR, at 800rpm, when before it wouldnt idle under 1000rpm or 12.5 AFR At WoT AFR is dipping into the low 10s sometimes even the 9s, so i will try the 125 mains again. Time for a few other things (there is always something!) REDUCING NOISE Steering tie rod vs exhaust downpipe interference caused a disconcerting rattle though the steering wheel on hard right (parking style) turns These pipes are 80's muffler shop specials and will be replaced eventually, meantime a wee tickle from Mr Grinder on the excess threads appears to have the desired effect INCREASING NOISE 'customised' some op shop $5 low impedance (6ohm) speakers using a skill saw, ply offcuts and builders adhesive that i really think have nailed the 'builders least favourite apprentice' aesthetic. They fit under the back of the seats where no one can see them, and are 11ty times better than the old 4inch pioneer box speakers, and were within my budget, I am not ashamed. Related, I also installed a switch so the head unit will run without the key in the ON position (dash lights on, fuel pump chunting away). This hack is needed because my 'cheapest on ebay' Ducato ignition switch doesn't have a flippin ACC position. Now that's austerity. Chucked on a new sticker holder sticker And piled the girls in for a hoon. For the first time it feels like its actually running well, which means i will be using it quite a bit more.

    Mine dont quite go that lean (22 = no gas?) , but there is a definite stumble and AFR peak on some low throttle transitions How did you solve it? Reading my new books suggest a range of potential causes/solutions: - idle jets to small, (45 fitted - i recon they will be slightly on the side of too big if anything) - idle mix too lean (AFRs say 12ish at idle, yet to plug chop to see what they say, and all the books say 'give the engine what it wants' to idle best ) - throttle plate position relative to 1st progression hole at idle incorrect The last two only require a screwdriver and time, the first one requires $ and new jets, and i dont think 45s are too small on a very mild 1600.

    I will count them soon, they are all in the 1.5 to 3 turn range, idle AFRs are in the 12-13 range with small adjustments either way was making a big difference. I will richen it up a bit no longer an issue after remove, trim and refit 'is it possible it might be messing with me' he asks! "possible"? POSSIBLE!!!!111!!1 (shakes head walking away, throws arms up dramatically)

    these ones had equal length shafts so i left them where they were and trimmed them Good Question! Mainly cause I used up my car time and had to do something else. Next day i did go for a hoon, went ok (better than the single carb!), but rich and lean spots and hanging on idle, etc, carbs not going back to idle in balance, etc So, I pulled off the carbs tweaked/ground back the linkage a bit more (master and slave levers were interfering with each other a bit), drilled the carbs mounting holes to 9mm (from 8.5) for that little extra bit of slack, reset the float levels, (12mm for these newer ones with a 26mm droop vs 8.5 and 15mm for the older style) pulled all the jets and gave them a clean out - two main jet stacks were not fully seated, and one accelerator pump jet was blocked ground some of the dizzy scoop on the manifold some more (while i could feel how thick the wall was with the carbs off) installed carbs and rebalanced/set idles etc hooned Great success, but does have a lean point off idle (progression holes?) and is a bit rich elsewhere esp on WoT, thinking of upping the mains to the 135 i have (up from 125) but also increasing the air corrector to reduce the richness at higher rpm (190 currently, no spares), but that is for later. Engine runs and pulls much better than with the single already, sounds great on song and has a pleasing burble at idle, and near silent on cruise with an instant response to stabs of the jandle. reccomended
  12. Rerouted the fuel line to how i planned it, with the fuel pressure gauge between the two carbs In a timely event, these turned up from @ul9601 and so after reading the relevant section i tuned my MAN-O-METER to 11 and made this very very boring and poorly shot video, which is pretty much the 2nd start after getting it to fire and idle and me tuning it by how tall the rod is on my MAN Engines really tappy! ill redo the shims soon. Next day i tuned it a bit more, 1. balancing the barrels on each carb to each other using the air bleed screws (bleed the highest reading to match the lowest) and idle (small adjsutments), then 2. then balancing the carbs to each other (bleed the highest to the lowest side), then 3. adjusting the idle mix (leanest smooth idle, turn 1/2 turn one way at a time until it slows, then back the other way until speed drops then keep halving the difference until you find the spot 1/4 turn above the lean speed drop point) and back around to step 1 again, etc Turned out the timing was pretty retarded too, but also found a better dizzy spot. Had a dig though the filters stash to see what would work. The big factory thing is the Strada Abarth manifold (fwd) and the blue line is wehre i would need to cut it Tuned out only the worlds greatest filter will fit. Even then the (K&N) bases needed a tweak to fit (My 125 Belina has socks over trumpets) RACE MODE (now i see it in the photo, I dont like the look of those trumpet retaining bolts just waiting to wiggle out and fall into the carb. NO SIR) However, small children and animals no longer in danger of ingestion. Check the clearance to the shock tower. Be a real faff to make the Strada filter thing fit unfortunately, would need a custom airbox and a cut and shut, but would also be better than the Ramflows Test drive soon
  13. Stage 7 - gosh! getting it going i would start with the basic factory settings (8-10deg seems about right) and adjust (via dyno?) from there - high power engines are generally set up based on the maximum all in timing (just back from pinking) with idle timing adjusted, if required, to suit However you want it to just run first if its cranking not firing you might have the timing 180 deg out - but start with the basics - got spark Y/N? - got fuel Y/N? - Got air Y/N? if yes to all the above, then check its at 10^deg (static) and once running, tweak from there

    i suspect your are 100% correct, but i dont have or have ever seen carbs with that style throttle shaft , and it would complicate both the linkage requirements (two separate pull points) and carb balancing significantly. What is even more silly is that if both barrel pairs were angled the same as (or more, for better dizzy clearance) as the front pair, they would fit perfectly, and there almost no space restrictions towards the firewall that justifies the choices they made. These were NZ designed and made specifically to fit sideys to the dealer developed 125T , with the advantage over the factory LHD models in that the carbs dont compete for space with the steering shaft and brake master/booster (all LHD RWD twin cams had twin downdrafts, or single carbs), so it seems weird to design it in such a way as to require special unicorn model carbs (both dellortos and webers were fitted), and to invite ignition timing/shorting issues eg if i was designing some to be made i would have designed them like this "\\\\"* instead of like this ")\||" *which is ironically pretty reminiscent of the /F/I/A/T/ corporate logo at the time
  15. Finally went and got ol mate @EURON8 to ally weld the holes in the already hacked up side draft manifold so i could space the carbs apart about 4mm from where they were but without fouling on the dizzy or loosing room to seal or flow. some careful 'linishing' later Without any trimming the inner barrells will be 49mm apart, manifold spacing is 40mm, min i can get away with on the carbs is 45mm, max on the manifold is 44mm. its pretty flippin tight and doesnt add up... shaft need trimming by 3 to 4mm and the nuts thinned down a bit as well - i ended up spinning about 3 out of the vice, so i need some more M7 nuts to fit back on the venturi retainers i stole my spares from! no need for retaining washers :/ You can also see how offset the carbs are to the manifold Redrilled and tapped - had to open a old NOS packet to get a 5/16 NSP tap out that had been floating around in my grandads too box for who knows how long before that Fitting the o ring holders show where the manifold needs a smidge of smoothing, about 15 seconds with the belt file. The outer edge of the o-ring diameter is just inside the edge of the manifold face. linkage mod, toyota corolla cable from the old single carb set up to twin weber linkage, all this is sandwiched between the carbs boom AS mentioned in a previous post, these carbs came from a very hot mini, and apart from the drilled and soldered main jets, they all looked very close to what various books and setting tables suggest would be ok for 1500-1700cc engines. 32mm chokes, F9 tubes, 45 idles, 185 airs and random sized but soldered and redrilled mains I had previously ordered 125,and 135 mains so popped in the 125 to start with. old manifold off. Removed the (pretty new) old leaky mechanical fuel pump for good, and installed a factory engine blanking plate. Dumb photo cause it shows the old pump. installed and with new linkage mount and brake vacuum routing, both way better than before. Fuel hose routing will eventually be jiggled to look better (i had orignially wanted to have fule coming in from the firewalll side, but the double ended banjo is a bit long to have the hose make the remaining curve without a kink or rubbing. May try bending it a bit, or maybe just buy a bent one. Clearance is ok, but I cant install the bell mouth into cylinder 3, nor will the air filters i have fit - i will look into making an airbox - i have a Strada 125TC airbox with 'ABARTH' and a scorpion stamped on it that i really really want to make work some how but whatever, lets worry about that after! plugged the fuel in, then spend an age jiggled the timing around and carefully power filing the manifold, then trying to find the best combo of a limited ability to clock the dizzy (it fits in only two more or less fixed positions, maybe 5 degrees rotation?) and dizzy drive tooth alignment , and then it fired up and idled. and revved. Sounds good, and AFRs are ball park YAY! DOORTS!
