  1. Part of the adjustment involves having the upright link rod (which is adjustable) set so that with an (i forget what size) drill bit through the holes in the pivot arm which bolts to the back two bolts on the left hand side of the manifold they line up. (Youll see the holes, and click, ah, thats what theyre for) sometimes the standard adjustment gets cocked over by an aftermarket manifold. Although your edlebrock LD4B was available through direct connection back in the day. (Mine has a chrysler part number on it) so youd hope* that its not too dissimilar in fitment to a factory item. 

    Lots of higher rise manifold cock things about. The kickdown arm on the trans controls the line pressure to (i think) the kickdown band servo* 

    *dont take as gospel 

    And if its not set right, shit slips and frictions burn up.

    Yip, pretty fucked/missing bits

    If you just want a bare engine missing covers etc I can probably sort something, they've been sitting outside sans tappet cover, side cover and oil filler etc

    Oh hi guys. 

    me and @Truenotch are on a XR250 collection mission to Christchurch on labour weekend, is anyone around keen for an impromptu meat and sharnathon?

    @- i5oogt - @RUNAMUCK @DoBro Jesus @JustHarry @Chris.QCR and everyone else!! 

    keen for anything, beers at pub, cruise into the hills or burn pile at borts whatdya reckon 

    This is a most disadventagous choice of dates. That weekend im scheduled to be pesting in another part of the mighty Te Waiponamu. Ill be sharning up a storm and sinking wanker beers with one of spam threads more notorious OS 1337 GCs.

    Please get offensively drunk, and someone spin an impossibly protracted and convaluted sharn in my absence. And know that although the rear window of a 1996 toyota surf is unlikely to rate a mention, that ill be there in spirit........

  4. And i love that bike too!

    I havent begrudged a single penny that needed to be spent on it either. Its been an investment in piece of mind. 

    I have replaced the rear wheel though. The places its been since you sold it make the roughest part of the Motu road, look like the Aukland motorway. (Not an exaggeration either)

    Turns out the previous owner had hard wired the kill wire to earth so it was never going to run.

    Disconnect wire, squirt of CRC, couple of pulls and it burst into life.

    5hp should make the shopping trolley boogie.

    Brother, be forewarned!

    You are teetering of the precipice of the ultimate Barry rabbithole.

    But its okay, ive been down there, so you dont have to. Some years ago, i repowered my childhood go kart with a 5hp briggs. In my research, i discovered a forum, dedicated to these engines. The Wisconsin Karting federation have a class just for them. I did some reading, and learned a lot. Firstly, mine had a thread in the exhaust port. Reportedly they go better with the pipe screwed in. (The ex port diameter is too large for optimal performance) naturally the shape where the pipe ends (inside the block) is also critical. They were all about a threaded sleeve that screwed into the ex port to narrow it down. (This may, or may not be "class legal" for the stock engine class. Theres also an optimum length for the pipe too. (Seeing as its just a straight pipe, its not hard to make) my memory isnt what it once was, but it was 12" or 14".  

    There are two types of 5hp blocks. The cast iron sleeve ( industrial motor) and the full alloy "cool bore" block. The alloy bore motor needs a piston which has been hard chromed. Otherwise the two soft metals gall each other. Theres also two varieties of side cover. one has a bearing, and th other the crank shaft just runs on the aluminium casting. The greatest weakness is the lubrication system. Theyre splash fed. Theres a sheet metal "dipper" bolted to the conrod cap bolts. This splashes the oil up to where its needed. Reportedly at apporox 4000rpms, this breaks off. And shortly there after the conrod snaps in two. And you get a window in the front of the block. (They say you can change the parts, and use pop rivits and RTV to make the block go another roound) 

    Better parts have the dipper cast into the rod cap. Believe it or not, there is (or at least was) untold aftermarket parts available. Wiesco pistons, carrillo rods, brand name camshafts.

    You can even get aftermarket billet blocks. (I think theyre called blockzilla 3?) 

    Now im sure youre only interested is the basic stuff to begin with.

    Firstly that pipe is a negligable cost improvement. And as tempting as it might be, dont shave the head. The air speed is highest up near the roof of the chamber. Skimming the head to try bump compression will hurt the flow.

    Looking at the block with the head off, youll see an "eyebrow" between the valves and the cylinder. You can grind with down the cylinder wall, almost to where the top ring sits at TDC. Again the air speed is low down here, but its a free mod for moar power.

    Now that the speed limit on my daily commute has been lowered to 80kmh max (WANKERS) I have been having my usual retarded ideas of buying something cheap to run for the 70km round trip. If something like that could do 35km each way at 80kmh max, it would be cheap motoring (apart from purchase price obvs) and be a bit of fun to go for a hoon on now and then.

    Man, if only you could find an NBC110! 

    Such a motorcycle would be ideal for the parameters outlined above.......

    any recomendation for 2013 volvo v40 T5r 2.0 for the same job in chch?

    @GuyWithAviators do you work for toyota now? or a non specific workshop? can you source volvo/good aftermarket parts?

    i can and very well might do the job myself but shopping around and realised ive not used a workshop in 15 years and have no clue anymore

    I use Nic and Christchurch automotive services. He lives just around the corner from me. Works from a workshop in his back yard. Super nice bloke, and dies good honest work at a fair price. Hes who I pay to do all the cunty jobs I cbf with. (Most jobs on modern cars, bar oil changes and brake pads basically)
