head gasket thickness how much is too much?
crider:
Paul, no it is idling that high with the butterflys completely closed. That is what had me thinking that I have a vacuum leak
Paul New:
hmmm yes that is kind of tough, do you have another carb you could try? a known carb that is working on someone else's car would be best that would rule it out.
crider:
No, i wish I did, but I've been away from racing for too long now. Don't really know anyone locally to borrow one from
crider:
I'm glad to report that I finally got the engine to Idle down, thanks to Bk for the tip on the headers. I slipped some extensions on the end of the pipes this evening and it took my problem away. I can idle it down as low as need be now. Thanks to everyone that offered suggestions. I may get to run this thing before the snow flys this winter after all
MikenMpls:
I would have never thought that carbs are that sensitive to issues past the intake valve but I guess it makes sense. When the intake valve is open its all one signal to the carb. Wow!
