Well I bought a used 2006 Yazoo Kees Max 2 with a Kawasaki 27 hp. (1497 hrs) Would not crank, so took to shop and the timing was off due to flywheel pin being sheared. Cranked & ran fine the mechanic said. Well.....he called me the next morning before I was to pick it up and said all oil had drained out on the ground. Probably top crank seal he said, but he would go ahead & replace all seals if it were him. After some researching online, I see this is a BIG PROBLEM with this engine. (no bearing replacement made to fix the problem & apparently no options short of trying to modify an off sized bearing to fit or just replace the engine itself) At least that's the only options I could find. If anyone has some positive results dealing with this problem, I sure would like to hear about it.
