I blew my engine thought it was bad gas it pinged to death ate one pistonwell had some damage ,
and cracked rod bearings in half then after sending crank and rods to shop I was cleaning up parts and took oil pump drive apart and thats when I noticed the shaft was stripped the hex was now round so my failure was indeed the oil pump was not turning at speed it made 30 lbs at idle but would drop at 2000-3000 rpms then climb back up at 5000 rpms due to shaft slipping .
have extra sshaft and gear but would like to install a heavier unit.
anyone know who makes one?????
