    Honda Gx390 Will not Rev up over Idle.

    Could be a warped head. May be related to the blown head gasket. Check on a table or with straight edge

    Got an engine. It's a former UAS motor from the Mid-Atlantic States. Going to do some top end work on it. New cylinder, piston and head work.

    DAYTONA 2019

    Yes, got that sorted out fairly well. Ran a one to one ratio belt drive from the crank to the jackshaft and a 2.2 final drive ratio from the jackshaft to the sprocket using 428 chain and 4 disc Bully clutch. It kept us at 6700rpm alone and up to 7000rpm in the draft.

    DAYTONA 2019

    Flat top: Looks like the rod went. Not sure if it was the rod cap that pulled out or if it snapped mid-shaft.
