Car sputters

ha, well since reading and responding to this post, i had to have my tank dropped and cleaned...now I'VE got a leak at the ring! i developed a bad stall issue, was a rusted out and gunked up screen and i forgot to check my fuel filter (which i knew needed to be done, but with everything else it just sort of forgot about it...). also, something as simple as choke idle can do it, but there's also the choke thermostat to consider.
