How to: unstick piston rings

This is a simple mix to unglue rings that are seized onto the piston. It has worked very well for me on a 21 year old Lawn-Boy. Mix 30% of transmission oil and 70% of regular oil together. Replace the oil in the mower with this mix and run the mower a few times with this mix. Make sure to change the oil after, because transmission oil is very abrasive since it has many detergents in it.

That also could work! It is mainly because of the detergents. I wouldn't try it on a car tho:tongue:

Never had very much experience with 2 cycle lawn mowers, But I have had with 2 cycle snowmobiles. You say to run the mower with your oil mix in it. I have found with the snowmobiles they wouldn't start. As I recall I would end up removing the piston and that the rings would beak taking them out of the grove and end up buying new rings.

Well, it was maybe too late for you, but I was able to start up no problem. I mowed my lawn twice. I will change the oil this week now to SAE30.

I agree 100%. Now I have had rings stuck to the cylinder wall and free them up and they will start after. I guess also are we talking about the same type engine 2cycle or 4 cycle engines?
