Default Re: Revs fine with no load, Boggs when clutch engaged.

What does the plug look like?
If it is pretty white you may have an air leak, it could be the intake manifold, carb gasket, or the motor seals.

If you have the new CNS carb with the blue cone air filter don't clean it with solvent, drop it in a bucket of Dawn dish detergent and hot water, let it soak awhile, swirl it around, rinse it off and let it dry.
