Thread: Timing Questions

Tweet

Your timming is fine you may have too hot of spark plugs heat range or there some hot spot on your combustion chamber of your heads cause one to try to run after the key is off.

Hey guys, thanks for the feedback. Without the benefit of an air/fuel meter I'm only guessing at my idle setting, but eliminating the timing side of this will hopefully make troubleshooting easier.
Thanks for being here for guys like me.

Due to the size of your cam, it sounds like the butterflys are open beyond the range of the idling circuits. You can drill a small hole in the front half of the primary butterflys ( I use 3/16" or less ). This will allow you to close the butterflies, but still get air. I found this tip in "How to Hot Rod a SBC".

I used this trick on a roller cammed BBC and a SBC. Worked like a charm and improved idle quality.
