2pg cylinder clerance

I'm rebuilding my 84 ezgo. Is .003 the correct cylinder clearance? To me it seems kinda tight for an air cooled motor.

I'm not sure what you mean by cylinder clearance.

The manual says piston ring end gap is .008-.016.

Engine specs start at section H of the manual.

Piston to cylinder running clearance. The manual states .0075 is max .003 - .004 is optimum, to me being air cooled I would think with running temps and expansion you run the risk of lockup. Just my opinion but I'll run with the specs given.

Welcome to BGW

.003-.004 is correct clearance. After the rebuild mix the first tank at 40:1 which will make it seem sluggish for the first tank then will wake up after refilling at 128:1 there after. Have a spare plug laying around for the future.

Thanks for the info I rebuilt the motor with the clearances and is running great after a couple of quick adjustments ( had throttle cable a little too loose and was backfiring from time to time) thanks for the help
