H engine vibration

Posted by JBW on June 26, 2005 at 07:15:50 from (24.241.16.173):

My 43 H was overhauled with new valves, sleeves, pistons, rings, bearings, ground crank, resurfaced flywheel and new clutch. It runs much better, except it has a vibration (as it did before the rebuild) at around 1/3 throttle. It smoothes out at higher speeds, but at 1/3, it vibrates everything. Could the flywheel have somehow warped over the years and gotten out of balance ? Is this common ? I’m sure its coming from the engine as I’ve taken off the water pump belt and the vibration is still there when the clutch is pushed in. Thanks for any help.
