As disclosed in the past, I'm am no mechanic.
I have a rebuilt stock 71 340 with a Harms built thermoquad. I just got the car running mint and it has about 600 miles on it now. The last two times I drove it, it starts up and runs perfect until it get hot then it does not want to idle in drive. It will stall at red lights if I don't put the car in neutral. It starts right back up but I have to hurry up and rev it up and throw it into gear to get it to take off with out stalling. Tonight, I tried to raise up the idle a bit cause I thought it was a little low (about 700 in neutral). I was doing this after driving it home from a cruise (running for about 25 minutes).
I raised the neutral idle as far as I could with the idle screw (about 840) and after that the car wants to stall every time I put it in gear. The car was running another 10 minutes or so while I adjusted the idle so it was pretty warm at this point. It also now seemed to be loading up a bit like it was choking out. (even in neutral) This is the first time it has acted like this since I got it running good.
Any ideas on what could be going on? I will have to get my mechanic to look at it but I am trying to learn as I go so I always start here.
You guys rock. As always, thanks for any help..
