Blue thunder, ignition module is NEW (not a rebuild) and 2 weeks old. Pertronix ignition module, drop in replacement. Engine starts good and runs smooth with new module. It started and ran with original equipment module, but not smooth like now.

This could be a fuel system problem. The fuel line setup is as follows - aluminum fuel tank, excellent shape. Pickup tube looks good and pickup end is situated roughly 1/4" from the bottom of the tank. A rubber fuel line (about 14 years old) connects the pickup to the fuel filter (spin on "looks like an oil filter" type). Metal line runs from filter to the fuel pump (looks good, no kinks, wear, etc.) New metal line (no kinks, etc, no obstructions) runs from the fuel pump (it's a NEW mechanical fuel pump) to the carb. Carb was rebuilt in May. The choke could be sticking, or maybe the float is not setup correctly, or other. I'm open to suggestions.

Should I replace the rubber line from the tank to the fuel filter? Very easy to do, and it's possible the inner part does have deterioration (??).
