activating the primer, buy pushing the key, say fuel starvation problem, air leak, weak fuel pump, carb contamination, dirty filters, remove the black cover on the fuel pump, see if there is trash in the screen. becareful of the orings. also misadjusted low speed needle, see TOP SECRET FILE for adjustments. you have 2 fixed jets, and 1 adjustable.
