So for cold starts two pumps and she will fire right up but if engine is warm, like when getting gas or running errands, I can pump as much as I want but get nothing so I have to crank it with WOT and that gives me about 50% chance of start up. Failing that it takes about 30 minutes for it to cool down enough to want to start. I have a carter afb on a 350 and am wondering if choke is supposed to close on warm start or is that just on cold? I guess I just figured when I put the clutch all the way to the floor on warm start up it would close choke. maybe I just invented that in my head . Obviously I am a noob so any thoughts, advice , or trouble shooting would be great.
