My car with a 307 starts well when cold , but has always had issues restarting when the engine is hot , and now we are into above average summer temperatures . The car will restart but runs rough and takes a while for the engine to sort it self out . So cannot restart and just start driving , i have to wait until it sounds normal or it will stall , and i will be into another restart . To make sure the engine has less issues restarting i lift the hood when i get somewhere to let the heat out . and when i get home i lift the hood to let the heat out . So any ideas what i can do to have less hot restarting issues ? or no hot engine restart issues ?
Part of problem may be ethanol in the fuel , i see on internet ethanol boils at 180 F
have turned the air cleaner up side down , this has helped a bit , maybe it lets boiling fuel vapour out . have disconnected and plugged off vacume hose from carb to charcoal canister the other hose goes to fuel tank this i think may reduce sucking in fuel vapours from tank .
next thing would be replace carb gasket with something that reduces heat transfer to carb.
Carb is a Rochester QuadraJet with the Hot air tubes to choke
