well the subject pretty much says it...i have to crank and crank when i start the motor hot. give it a little gas...crank some more...i get the best results if i press it once and hold the petal to the floor to start it. but i hate doing that because it usually revvs the crap out of the motor when its first starting and i hate to do that to oil starved bearings. when it does start, it runs like crap and i usually have to gas it up a bit to get it normal. it's a carbed motor, edelbrock 600cfm and a regular old vac advance distributor. also dont have an egr. new mech fuel pump...clean filter...cant think of much else, what do you guys think?

Does it crank really slowly when hot? If so, the first thing I would look at is backing off the timing. If you have it too far advanced, it could cause this very problem.

had this same problem with my older car with holley 650..... when i shut off the car.... gas would still be filling in the carb.. i could see the vapors.... check the float sight holes... it might be set too high. gas should just trickle out when level!!... hope this might help!!
