A few years ago my husband and I purchased 2 Bolens 12BB01 Power Ho Deluxes with 2 sickle mowers and a reel mower. It will take both tractors to make one good one with the exception of engines. On the one engine the flywheel had worked loose and widened the keyway slot in both the crank and the flywheel. The other engine the crank is worn beyond specs and the flywheel has a broken vane. Although we have found many parts for these engines on ebay, we have not been able to find the crank or flywheel. We haven't been able to find any parts through on line searches either. Is there any place that a member on GT would recommend to look or call? Any help would be appreciated.
