Picked up a 75 F150 with a 390 bored 60 over couple days ago. Fella I got the truck off of dumped major buck into the engine did that easy wireing system the $600 rewireing thing. So heres the problem/ what is worring me I should say. It takes 1 to 2 minutes to get its started. It sits and cranks like it wants to turn over then it will die down like its going to just stop cranking and then it turns over. I want to say flooding or maybe the carb is getting to hot and evaporating the fuel but it does it after its been sitting for awhile. so give me some input plz.
