Pierburg Carburettor for 318 M10 - allisbmw
I'm having trouble a getting my BMW 318 M10 to idle properly.
When it's warm the engine hunts, like it cannot find its medium. I have recently had the motor overhauled and the mechanic who took it apart did not take note of where the vacuum pipes went thus I'm unable to drive the car until I can resolve this problem as too little REVS causes the car to cut out when approaching traffic lights, etc. Just to mention, the two jets on the very top of the carb do not seem to be working correctly as no fuel seems to ever come out of them. I'm not sure if this is a result of the vacuum pipes not being in their correct positions. Just for a description, it has a big white electric module on the left side if you are standing over the cylinder head on the drivers side. Is it possible you have a diagram of this carburettor that can possibly enable me to return these vacuum pipes to their correct positions? I believe the carb is a Pierburg 2B4 model if I'm not mistaken. Any assistance would be appreciated.

yeah the pierburg carb is a terible carb the automatic choke goes wroung with them eventaually most people change them for a webber. im replacing mine with webber 32/36 at the monent fitting it to a solex bmw intake manifold. this carb doesnt fit the zenith pierburg stud patten hence using the solex manifold as fitted to pre 1980 carb 4cyl models from around early 70's. but you can get a 32/34 webber replacement carbwww.fastroadcars.co.uk/shop/index.php?act=viewProd&productId=12. the revs on mine at idle often flutute occationally stalling if not reved. the choke mecanism is partly stuck on so scrapped its mot emishions this year so thought id fit webber carb. il have a look a vacume lines but really complex on them.
pity we cant understand this but it's got pics:
