For the last 3 years every Sunday evening after church I drive my roadster pickup to visit my mother that lives in a rest home. I drive a 60 mile round trip. For the last 2 years on my way back home the engine pops and dies with in 100 yards of the same place every Sunday. I have drained and cleaned the gas tank, I only buy gas with out ethanol, I keep it tuned up good. All I have to do is loosen the strained on the zenith carb and let a small amount of gas run out and it always has plenty of pressure there but never have any rust. I screw it back and climb in and resume driving at 40 to 50 mph. Haven't missed a Sunday in two years.
