| Are you using the correct fan collets?It sounds to me like you are not using the correct collet set for the YS. The lower collet, next to the front bearing of the engine, is the same for almost all engines. The upper collet, under the nut, should fit the threaded portion of the crankshaft tightly. You should also use the washer that came with the engine under the lower collet.
