Was running ok then recently starting stalling at rest or moving when the accelerator was pressed down half way, you have to ease the revs up slowly. I'm looking for tips before I start tearing the carb apart, sounds like the accelerator pump but could it be a fuel line problem, should I start at the tank and work forward or just start on the carb? Have recently changed plugs, wires, rotor and cap. I'm working on this isn't timing or electrical, but... Doug.
