Rough start after initial start

Hey guys, been having this issue for awhile now and its getting irritating. Ok well initial starts are simple. Pump gas 2-3 times and boom she fires right up with no problem. Go to put in garage or drive for a few mins and shut it off and go to restart and im getting alot of hesitation. ill crank it for 3-5 seconds and sometimes got to pump the pedal a few times as well.

Any ideas? THANKS GUYS!

Sounds like the engine isn't running long enough to come up to full temp and the choke isn't right for the "time frame"; so to speak.

If you fire her up and drive for a 1/2 hour or so do you have the same problem? A short trip might allow the choke to come off but the engine still needs choke to start.

Could be a combo of timing, vac advance, and choke setting....

If i dont recall when i have driven it on the highway, then shortly after it was ok. Well over the last year honestly it has only been driven less than 100 mi. Only been driven to body shop and a few times to my place a few times. And also since u mentioned the carb settings that was brought to my attention once before. Thanks for the input!!

You're not supposed to pump the pedal at all before starting a carbureted engine.

Cold start: press (and release) the pedal once to load the choke.

Warm start: hold the pedal down slightly while the engine is cranking, release when it fires.

Anythink more than that is going to cause flooding. If pumping the pedal isn't causing your problem, it's at least adding on top of a pre-existing problem.
