Well I was wondering what anyone thought of this. The first pic is when i pull the prop toward the front of the engine there is a gap between the prop driver and the case (see red arrow). In the second image, i pushed the shaft in toward the back. I believe that piece is called the prop driver, the driver is not moving on the shaft but the whole shaft is moving.

The driver actually snaps into the case as shown in pic 2 but it pops back out as in pic 1 when i pull the prop forward. Is this play normal? I measured the movement to be about 2mm or 5/64" with my caliper. Is the driver supposed to be pressed in the case harder to prevent the shaft from moving?

I ran the engine just for a 30 seconds or for the first time since i bought it used. It seemed fine during idle and low rpms, no wierd noises. I ran out of time so i'll play more tomorrow. I did notice the shaft moving out/forward (pic one) when it started.


Thanks,
Ryan
