A little history on it first. As most know, I haven't had my car on the road long (just broke 300 miles today), only 5 months. Been tweaking on it and working on getting it just right. When the engine gets hot it has issues idling in gear, seems to be even worse in the 90° heat now. I had to turn the idle up to about 1600 just to get it to idle at 900 in gear, which is odd since I have a 3800 rpm converter (it won't even move at idle). I thought it may have been the carb getting hot, so I made a wood spacer this morning, no change. I can tell the carb is cooler than before, but it ran even worse today once hot. Going down the road it seems to run fine, but when I come to a light I have to hold my foot on the gas a little to keep it running sometimes. When the engine is cool, it runs fine, maybe 100 rpm change when I put it in gear.
I also realized that the engine gets pretty warm in this heat too. It got up to about 225° on me in a 20 minute trip, but only climbed at lights. When moving it would slowly drop temp, but go right back up at the next light. I believe I am going to get the Cleveland bypass block off plate and try a Windsor thermostat. I believe that will take care of it. I dont think it is a fan issue because when I got to my destination I let the fans run for maybe 2 minutes and it cooled it back down to under 200°. I think the thermostat "hat" isn't sealing against the bypass plate well.
At any rate, could the 2 be tied together? Or is there an issue with my carb that needs to be addressed? Holley DP by the way.
