[Cal Metal]

The phenolic spacer will help, as Tom indicated. Additionally, the OEM Weber needle/seats are not the best--one of the inherent weaknesses of the carb. There is an excellent factory replacement that prevents any leakage pass the float. Give me an email if you have any interest.

Let me ask the question. On all the puddling that is found on the throttle shafts, is it typically on the last carb; that is, the carb that accepts the end of the fuel line?
