Thermoquad idling issues
Recently started and broke in the cam on my 340 with a 750dp. I have a rebuilt Tomco Thermoquad 6138s from the 70s that has never been on a vehicle. I’ve wanted to try out a Thermoquad for awhile.
I don’t have the divorced Choke figured out or hooked up yet. I was able to get the car up to temp by holding the throttle around 1500-2000 rpm.
Choke wide open, and I let of the throttle the car dies. I have to go almost 4 turns out in the idle air screws to get it to somewhat idle. Idle screw maxed. When I slightly close the choke the car revs up and runs clean.
The carb is very responsive when I snap the throttle, but will not idle.
Where should I start? I didn’t find a vacuum leak around the base gasket or anything.
