Ok Im proud of myself. Ive overhauled 2 strokes all my life (I was do it when I was 12). Now I finally got to do my 250f. I replaced the piston, checked the valves with solvent, they didnt leak but needed adjustment. Did that and put it all back together. The cam chain got kinked up on the crank gear so I had to remove the mag and stator to fix it. Got it all back together and it fired up on the 2nd kick. Im not sure why but I was kinda intimidated by it, hell I rebuild single and dual overhead cam Ford engines all the time for a living!
