Discussion thread for my two cars, both minor projects. //oldschool.co.nz/index.php?/topic/46070-mighty-joes-english-duo-cortina-67-triumph-74/ Joe.

G'day. Sorry if i'm breaking rules posting two at a time but i didn't think it was worth one a piece as they're both relatively small projects, if it's not allowed please let me know and i'll seperate them. These are my two, well the Cortina is mine and the Triumph is the Mrs... I put the Cortina, "Jess" in for a warrant today after a few months off the road running like a bag of spanners. she failed on a rear brake cylinder weeping so i replaced that this afternoon and the missus is dropping it off tomorrow and hopefully she'll be stickered up for the summer! Nothing flash under the bonnet but hopefully it'll prove functional and reliable which is enough for now. The Triumph, "Lola", is bang in the middle of some major cosmetic surgery. 40 years of Kiwi sun wasn't kind to the old girl and she was looking tired and well past her best. After she failed Warrant in august on dreaded rust the decision was made to take her off the road, fix her properly and have something a little more "fun" rather than just weld her up and keep on going. an old picture after we'd not long had her. Taken a few weeks ago. The Colour scheme for the Triumph

It runs! I got a Haynes "Weber carburetors" book from the library and it says 8.5mm closed 15mm open for the floats. They were way off that. i've guestimated the gap cos i don't have a set of drill bits at home. but it starts first time now, no throttle. Cheers for the suggestions. i'll get it to the workshop at the weekend and play with it there where the boss has more tools. Now i have some tuning to do with it. Cylinders 1 and 2 are dry fouled, and 3 and 4 wet. which is really odd as the way the manifold splits the carb is 1 and 4 off the rear barrel, 2 and 3 off the front one. All good though at least i can get to tuning it now. needs a good run to warm up and then i can see what its doing. They could just be fouled from when it wouldn't start before. Cheers for all the help and suggestions. Joe.

the carbs came off another 1500 pre crossflow track car with a ported head and pretty fresh bottom end but he was running 2 together. I have the other carb too but was going to run 1 as i thought it'd be easier to tune! ha. Thats also why i increased the idle jet size as per what i'd read. fuel pressure is set at 1.5psi. i haven't touched the floats, thats where i'll start tomorrow. Cheers. i'll report back.

I've got a single weber DCOE 40 on a 1500cc pre crosslfow. it won't start from cold. like, not at all. to get it running i have to stick on the jump leads and crank it for 45 seconds to a minute, choke on full, pumping the throttle and it'll splutter to life about 50% of the time. the other 50% it'll flood the plugs and when i swap them out for a dry set it'll start with a few cranks but there is fuel leaking from the top of the carb, from the jet cover. I've checked everything i can think of, and tried various adjustments of the air mixture screws. starting from 1/2 a turn out all the way to 4 turns out ( i realise this is far too much but just kept on trying) it has a new dizzy cap and rotor, leads, plugs, i've double checked and treble checked the timing and firing order (1,2,4,3 on these weird engines) it's running the stock lift pump, with a malpassi filter king regulator (with a setup gauge) The carb is a dcoe 40 on a spear (lynx style) manifold. 34mm chokes, 165 main jets, 55 F8 idle jets (but have tried with 45 F8, still nothing) 45 pump jets. When it runs, it's alright. a bit rich but that's down to fine tuning. but i can't even get it to the rough running stage. and once it's started it'll restart without any gas or choke, just straight into life. its got me beat and i'm well pissed off with it. Any help hugely appreciated. Joe.
