Thanks for last two replies today.

I just turned the mixture screws in all the way one at a time from 1 1/2 turns and it decreased RPM from 850 to 550 but did not stall engine.

I can't check timing right now because when I installed a new water pump I also installed a new harmonic balancer and adjustable timing pointer. So I need to find TDC again to get the pointer right and will then check timing again.

One thing of note is my vacuum advance is connected to port (passenger) vacuum on my Edelbrock 750 carb.

Thanks again!
