RSWYAN: Had to laugh, that's exactly what happened to the first motor. Man can those Hong Kong motors smoke!:laughing: Took out the setscrew on the stop and put a shaft collar behind the stop. This allows the stop to remain in selected position, but it can be rotated away from the end of the part, before cutting, so it won't bind at the end of the cut.
LD1: I stumbled across this by accident. Your local lawn mower shop can help. Tecumseh has a product called bentonite, comes in a squeeze tube. The stuff isn't cheap, but less than bronze heli gears. $20 for a quart tube. Drain all the 90wt. gear oil out and replace with this medium bodied grease. It will lubricate those high pressure gear surfaces even in cold climates, and will cut down on "seeping" around the shaft seals. Also I found that the blade just needs to be tight enough to not slip, but just enough to make a straight cut. If your saw is cutting on a curve, as it drops down, replace the blade. Too tight a blade flattens the teeth on one side of the blade as it goes around the drive/guide pulleys after prolonged use. 445A
