Would anyone know the size of the jet used for the fuel mixture in a Weber 32/36 DFV carb? Mechanic working on my car cannot get the fuel mixture straightened out (too rich) and has suggested I order 3 progressively smaller jets for him to try. This doesn't sound too difficult, but I don't know the size I am starting with. If no one on the board knows, any suggestions on where I can find this info?
I know a single carb is not the ideal set up, but it's what I own at present. Thanks in advance for the help. |

Have you ever talked to a VW mechanic about people who remove the heat risers from their engines? If you do, be prepared to learn some new curse words...
Those are major factors as to why the single-carb setup works better in the Type I motors than in the Type IV motors. I talked to mrholland2 at the last 9:14 breakfast up at Alice's, and it sounds like his cobbled-together setup may actually make the dreaded Weber Progressive work decently. He has heat exchanger air ducted into the carb, which helps with the icing and mixture drop-out problems. A pair of baby carbs (e.g., single-throat 36es or a similar small throat, single or dual throat) would likely work OK and might get better fuel mileage, at the expense of top-end power. I have heard someone on one of the forums say that they got good mileage and lousy top-end from a pair of small carbs. So it might be one way to go. But then, that will be fighting against the carb camshaft, which is optimized for better top-end and not for low-RPM running. So.... --DD |
