SWEET!!! After I removed the sleeve, I got the piston and connecting rod out. Thanks for the help.
I hait to assume, but it's cheaper to rebuild versus buying a new enigine. I figured I would go ahead and replace the clyinder head, piston, sleeve, connecting rod, pin and c clip.
What is the difference in the washer that's between the cylinder head and piston sleeve?
Thicker: more compression
Thinner: less compression
Thanks again for your knowledge and help.
Are you talking about the shims on the head button that sits onto the sleeve? If so different engines have different size shims with different thickness. My os 28 has 2 thin and 1 thicker shim. I left all 3 shims on for breakin then took 1 thin 1 out.
Less shims gives more compression which can give more power but to much compression results in early detonation in the chamber which can damage the engine. Research the engine and see how many shims you need.
Pitting on the piston head and button can be a result of early detonation. I damaged an os28 last year because i took 1 to many shims out it badly pitted the piston and button.
I would only rebuild an engine if it was an expensive engine. Most cheap to mid range engine arent worth rebuilding. By the time you check the cost between the rebuild and upgrading to a better engine it isnt worth it.
