I have a 1981 Yamaha PW 50 that I can't seem to get running. It didn't run when I got it. I have tried cleaning out the carburetor (which is like new), installed new reeds, piston & Cylinder (had low compression), new stator and flywheel (didn't have any spark and the flywheel had a broken magnet),new handlebar switch, new CDI box, new coil, new spark plugs (tried a couple NGK's). At one time it ran for about 5 minutes, but the engine ran backwards (hit the gas and the tire turned backward). It has not run since. It has great spark, is getting fuel to the combustion chamber, it must be out of time, which is not adjustable. I've never had this problem ever with a 2 stroke, and this headache is making me NEVER want to buy a Yamaha EVER again (I've had a couple that needed constant attention and repairs, and they were fairly new!!!) I have even blocked off the oil injection and plugged the carb to run pre-mix fuel. When the engine ran backwards, the kick starter turns the engine clockwise which the manual says is correct, but would cough just enough to start running, backwards.......I've wasted a lot of valuable time on this thing. I even went and bought a Suzuki 50, just because it did run so the kids had something to ride.....RRRRRRRRRRR!!!!!!
