340 has a hard time starting when hot?
My car never did it unless you left it sit for 1/2 hr to 1 hr. Then when I went to start it to leave it it would have the problem. If I would leave the pump off it would fire right up and I would have to turn the pump off and on until fresh fuel came through. If I would turn the pump on first it would flood the motor and just crank while I held the throttle 1/2 way until it fired. The float would not close the needle with the hot fuel. I tried three different carbs . Proform, BLP, and a quikfuel. All did the same thing. After I eliminated the fuel being dead ended at the carb problem solved.
I would always sit at shows with the hood open. 100gph pump and regulator on 1/2 inch fuel line from tank to carb. This problem drove me crazy for a long time. We just finished a aluminum head 340 Demon and another iron head Duster. They do not have this problem for some reason. Tap the key on them and like my Duster .
Click-Vroom, every time. LOL> Some cars do have this problem that we get them here off and on.
I had one of those "Vroom" motors on my 20" bike when I was a kid. Click Vroom every time. Now unlike others I don't have my atmospheric pressure, temp, altitude, fuel mix, nor do I know my parallels at any elevation. My fuel was purple and I piss yellow. South end puts out different colors at times. What I can tell you is this is something to check when you run out of ideas.
