The engine splits verticaly and not like the newer generation of Poulans. The bearing on the mag end was too easy to slip into the case, so I used green loctite to secure it. It was the only cure for the loose fit that I could think of. I do not know if the gasoline will wash the loctite out or not. Even if it did I would not think it would do so in just a few minutes of running as the looseness in the crankshaft showed up as soon as the engine warmed up on the very first run. I am thinking I should tear it down again and see if I can find a problem. If the bearings are still tight in the case, then it would indicate increased play in the bearings when warm. Does anyone know how to pull a seal without damaging it? If I pull the seals I could see if the bearing moves in the case. If the bearing is loose in the case, then what? Is there a cure other than a new case?
