[QUOTE="Captain Ahab, post: 396448, member: 10"] Star with the easy stuff-replace those plugs (check teh wires as well - look for burn spots and cracks - if found replace Then try just pulling off and cleaning the bowl of the carb - might have some debris or gum in there - spray it out with carb cleaner. You can also try "de-carboning" using Sea foam - follow the directions on the can (may or may not help much but should not hurt anyway). Also, check your fuel lines to make sure the fitting are tight - the high speed "sputter" sounds like a slight fuel line vacuum leak [/QUOTE]
