i have an edelbrock performer electric choke carb and it works fine and everything but when i shut it off and let it sit for like 10minutes to an hour and go back out to start it then it just keeps turning over and over and over and will finally start but if i put the gas pedle to the floor then it helps and makes it start faster. how can i fix this? i also have problems when my car gets really warm at about 220 and i sit in traffic at an idle my car doesnt want to run. the idle goes way down below 500 and will barely stay running. not sure if it has anything to do with the carb or not. i also installed an xe 268h cam and edelbrock performer rpm intake. thanks alot!
