I picked up a Husky 41 for next to nothing at a garage sale. The owner was selling it as a parts saw. It looks absolutely brand new so I decided to try and fix it.
The cylinder, piston, and piston ring have scoring on the exhaust side. What typically cause's scoring???
I removed the piston ring and it looks slightly narrower in the middle than at the ends. Is that from wear or are they produced that way?
I polished most of the scoring off the piston and cylinder wall starting with 240 grid silicon carbide paper and ending at 600 grit. There are only 3 very slight vertical lines but it's way better than it was and you can't even feel the scoring anymore. Should I polish finer than 600 grit or should the cylinder have a courser than 600 grit pattern?? I want to avoid removing too much material.
I plan to buy a new piston ring. Would it be wise to remove the piston from the rod and rotate it 180 degrees to equalize the wear??
There's a cap that bolts to the underside of the cylinder. Should I use gasket sealant. Is there any pressure or vacuum on the underside of the cylinder?
I know the proper repair would be to replace the cylinder and piston assembly but I'm not going to spend $150 on a saw that I'm into for $5. Are there any other suggestions for my budget overhaul?
Thanks
