oooh! A real live carb problem (no efi tech!!)
Yeah, well. Check to see if you've got gas coming out of the upper part of the carb anywhere. Gas on the intake manifold would eventually smell on the inside of the car. If it starts hard either/both hot/cold, your float might be sticking and letting too much gas in & flooding it somewhat. Check your exhaust pipe with your finger - if you've got black but dry and sooty stuff, it's too much gas. Also, your choke could be sticking shut - either one would be somewhat relievd by depressing your gas pedal a ways down. Also, does the engine smoke black after it starts when this happens? Maybe your choke pull-off vacuum can is shot - they're available separately at any decent auto parts - it pulls the choke open a little when the engine is cold so it starts without flooding. It's hooked to your choke linkage with a small rod and is a little round can with one vac hose. Also, after the engine is warm, take off the air cleaner and see if the choke is fully open. If not, check the adjustment on the little round dark plastic housing index marks, and check the tube from your exhaust manifold to the choke housing - it can easily get plugged so heat doesn't reach the choke and open it. If it's plugged, get a large diameter wire or small rod and hammer one end flat. Put a vise grips on the other end and rotate it thru the tube like a drill bit, just don't push too hard. Also use some solvent to soak the hard stuff in the tube.
