My buddy just installed a ready to run distributer in a 400 with a thermoquad.
It will run with the lean burn un plugged , but its back firing thru the carb.

I thought there was something you had to do to the carb in this situation ? What are we missing here

I converted a 318 years ago and it ran fine without touching the carb
