Hello, I posted this in my rides thread but ill put it here too, I have recently put a weber 32/36 on my 4k and fitted extractors at the same time. The carby came off a 18RG? i think. I can't get it to idle stable. It seems to be very rich at idle. Have attempted to tune according to basic settings and will continue to surge at idle and when backed off from accelerating will drop and nearly stall. I have checked: 1/ Ignition timing - 10BTDC at idle and advance is working on acceleration. 2/ used starter spray to check for air leaks, couldnt find any. when i replaced it i replaced all gaskets including manifold gasket and used aviation sealant on carby and adaptor plate gaskets 3/ Have checekd jets, it has Primary/Secondary 140/135 mains 160/175 Air 50/55 Idle 4/ it idle very well before carby swap It has an electric fuel pump fitted which worked on standard carby with no problems My questionsn are 1/ Shoud the air jets be larger on the secondary instead of mains? 2/ Do i need a fuel return line, at the moment i have blocked it and i suspect this may be a problem? The red arrow is fuel in The green arrow is blocked fuel return the blue arrow is the vac adavance hose 3/ any other suggestions? Please see youtube video of what it is doing,
