i have the solution to the bearing fix, i took it to a small engine repair place and me and him worked to solve the bearing issue from moving outta place. as you can see in the pic we placed 2 washers machined within thousands on each side of the bearing so the bearing will not move out of place and stay in between the connecting rod center. I have the engine all back together and it runs smoooth and seem to hold up really well. He also honed( spell chec) the cylinder out a couple thousands. made alittle more power. new piston and rings.
Bigger cyclinder equals more power. took about 1 1/2 hours to do with a hone tool. My gashes where that deep we had no choice to keep honeing till the cylinder was smooth enouph for the new piston and rings. hope that intrigued you more
I can understand new rings, but why a new piston head, is it cracked? So if their are scratches in the cylinder, should it be honed? I know that I have some scratches in my cylinder, but I thought that this is normal. I have also noticed a decrease in power, mainly climbing hills. I don't know if you can answer this for me or not, but is the cylinder supposed to be scratch free? I would think that is impossible. Hmmm... Thanks for the help. oh yeah, maybe you already answered this, but where did you get the needle bearing at and how much did it cost? How much did it cost to hone your cylinder out?
