After about 15 minutes of running at full throttle the engine cuts back to about 50%, alternates between 50% speed and full speed. Motor does not miss, just like it got throttled back.<br />Things that have been done:<br />Carb. kit, new hoses, fuel pump kit & new plugs.<br />Plugs have good fire but the bottom plug has a little more oil residue than the top. Also used about 2 gallons of gas while running for about 30 to 40 minutes.<br />Could it be the coils or points and condenser?
