2 Strokes run WAY lean...

Just figured out the last tank of various 2 stroke and 4 mix equipment were run about 100 to 1. Making matters worse it was MY fault. Everything is still running, plugs looked pretty damn white...Wondering how much damage was done?

It is impossible to tell how much the rings dug into the cylinder, but I have brought units back after they have seized. I would run a higher than normal amount of oil in the gas for awhile. Don't run the engines for long periods of time for a week or so. I think you might be okay.

As long as they are not siezed and still have enough compression to run, I think you'll be okay. It has always amazed me how a two stroke lives under ANY circumstances.

Good luck,
