Thanks for the post. I currently have them set at 1 turn out, and the AFR is reading saturated rich. Since there are dual carburetors, maybe it's just too much fuel for idle on a 350?

This is where I do not have the answers, and will need to check on the weekend. I'm fairly certain I do not have enough total timing (or initial, for that matter). Right now I have set the motor at...

Thanks! I do love it, it's been a hobby now for a while. I had a single carburetor on it for a while with an Edelbrock RPM Air Gap intake, but she wasn't making enough power! This truck is a...

Hi,
