gee i love this forum if you havnt got anything helpful to tell me **** off to a different section, im trying to learn but im not being helped by many people, credit to some who have, thankyou but the rest of this has been pure crap, this thread could have been 3 replies long, and i wouldnt of cared cos i wouldnt of had people calling me stupid wen im not, if you think ur so good, tell me what the problem is, dont carry on about me being too young, get over it!!!
we can't tell you what the problem is, the only thing we can do is make a few suggestions, we've tried before - what Wolfman is saying is that it could be just about anything, or it could be a lot of things together all contributing to the problem. In your stalling thread, I suggested you take it to a mini place and get it tuned, take it to anyone and get it tuned.
Or, be nice to John Small and ask him to come and have a go at it for you, he lives nearby doesn't he? it's really really hard to diagnose a problem like this without specific details of what's set, or being infront of the car and actually working on it.
I could say that you have it very rich, as flames out the exhaust would suggest. What I would do in that case is reset the carb mixtures - read Makka's post. What the book says to do is take the dashpost off, and turn the mixture nut up till the jets are inline with the 'bridge' in the carb, then put the dashpots back on, make sure that the pistons actually fall all the way down, don't get stuck half way etc. Then lift the each piston with your finger and let it go, there should be a dull metallic thunk, if not, then the needle is out of alignment, fix that first. Next, turn the adjusting nuts down 2 complete turns. Then start the engine and set a fairly fast idle on each carb, by listening down the mouth of each carb through a rubber tube, get them to sound the same - sucking the same amount of air. Next thing to do is do the adjusting nuts up 1/4 of a turn each until the idle just starts to slow down, it should be at the lean point. There is a button under the dashpot on each carb that you can push up, push it slowly and it lifts the piston. Do it for each carb, if the engine dies down, then the mixture is too lean, if it picks up, then it's rich. Ideally, the engine should pick up slightly then settle back to the same idle. When you're done, adjust the idle speed to a nice idle, again making sure the carbs are sucking the same amount of air by listening with a rubber tube
that's the best advice I can give you on tuning twin carbs. And it's assuming that your distributor timing is correct

), and this is a public forum so i'm not going to "****" off (and really swearing AT someone? we're going to really warm to you now) we can suggest what we like, and hell it may even help someone else who has the same problem down the line...
