ENTDOC,

Did you ever solve the rich condition on your BB? Are you now running Webers on the GT40? If so, how does it run?

You may have seen my posts over this past weekend regarding my linkage problems. I think I have that part fixed, at least for now, but my engine is running pretty rich on the idle circuit. Like you and your BB, when I punch it, it looks as if a Mac truck just pulled out!

I am running a 351W with 185AFR heads, cam has 573 intake lift, 244 duration, 568 exhaust lift, 230 duration. Timing is 32 deg, emulsion tube F7, 145 main jets drilled to.058/120, 120 low speed air bleed, 70 idle jets and 120 high speed air bleed.

The engine runs great once the transition to the main circuit is made. No stumbling, except right near 2000rpm, which I think may be caused by flooding.

Any help any of you Weber experts can provide would be greatly appreciated!!

Thanks,

Gun Doc
