I bought a used g62 at a swap meet that has been converted to ch ingnition with a mechanical advance, the problem is that the sleve
that attatches to the mtr has come loose and moves fwd causing damange to the next sleve that rides over it. they now bind,so when the mtr runs at full throttle it starts to surge and then backfires and quits, my question is there replacement parts or a kit that can be purchased to fix this mtr, or is there someone that is good with these engine that you would recomend , thanks, goose
