My experience was no damage when I loaned a saw in the 70s and he did not use my mix vs his straight fuel without mix. I feel it was old gas that saved the saw. I disassembled the saw and found no damage. Today, I would only pull the muffler to inspect the Cylinder on 2 cycleâÂÂs vs the crank also. IMO you will have cyl damage before crank damage. Opinions??

This sounds like my recent concentration. Not Good!

I had a STIHL blower brought to me that had straight gas ran in it, locking it up. What I did was remove spark plug, sprayed a LOT of PB Blaster in it, and some oil....every day I would put a wooden dowel on top of piston through the plug hole, and gently tap it a few times. After a week or so, the piston moved...I was able to pull it through after that, though I did it very slowly....with plenty of oil in cylinder. It is still running, now 13 years later :)

Snuffy, that sounds like the sort of thing I was thinking of. What's PB blaster?

PB Blaster is penetrating oil ("thin oil is the point"). The same was recommended for a Zero Turn Mower that was run with low oil. It was forcer to turn by hand, and then started. A year later it is running without burning oil or symptoms of damages.

I keep my 2-stroke gas in a steel 1 gallon can. My red plastic 2.5 gal and 5 gal plastic cans only have gas (with stabil). When I need two stroke gas I always reach for the steel can. Don't see how I could ever make a mistake.

Okay, I got the piston to move a little. What now, put 2-cycle oil in the cylinder and move it slowly?

Keep working it. It may run again and may not. If you ran it till it siezed the piston you have definitely done damage and shortened it's life.
