Have you removed the sleeve yet? On all the 4 strokes I've rebuilt I've never had to use the hole to remove the wrist pin. Put it on tdc and pull the rod off the crank. Make sure you understand how to set the timing before pulling the cam.
Hey, yeah the sleeve is already removed. Had to remove the sleeve to get to the wrist pin. I wish it were easy to where I could remove the rod off the crank... But she moves a few mm and that's it. Wrist pin has it locked in pretty good. I think it's just how these engines are. I am thinking I won't need to adjust or mess with the timing. Just gonna replace bearings and then put it back together
@perkyplanesrc9363 glad to see your getting out of your comfort zone. 4 stroke are not scary once you understand them. Good luck! I just picked up a Lanier stinger with a os 1.20 4 stroke on it. I know it hasn't been in the air for at least 4 years. I might be doing one soon also!
The cylinder sleeve will cover the small scratches. It shouldn't be a problem. If the bearings feel okay, you might even skip pulling the wrist pin and the piston. You may be just creating extra work. Keep up posted on your progress. If you can find the Harry Higgley book called All About Engines, it gives you a lot of information on rebuilding a lot of the older engines.

@@perkyplanesrc9363 ok worth a shot. I haven't had to rebuild a 1.20 yet. You will need to remove the cam to get the crank out.
Well then I'll be doing the cam/timing afterall lol. (Homer Simpson "doh!" moment! )
This is the first 4 stroke I have ever cracked into.
