Had to replace pistol grip and cable, so off came air cleaner, carb and coil. Put everything back on and a unit that took one choke pull then one non-choke pull to start has become a bear to start. 8-9 HARD pulls. New plug, good fuel/air filters. Only variable I see is perhaps coil gap? Used a business card like the dealer suggested...Would like some comments before taking the whole thing back apart. Coil gap make a difference?
