|  Husky Gurus have a ? about pistons
Hey guys I have a 575xp and a 346xp and both have basically welded the ring into the piston. What causes this, neither saw is very old. I have alot of 2 stroke epuipment and its only happened to these. I run 50:1 ratio. Tell me what you guys think.

Heat, too lean mixture. Maybe poor quality 2 stroke oil or using mineral oil at 50:1 instead of synthetic. I do not run any saws on 50:1 regardless, rather have a rich saw with a bit of smoke than a stuffed saw. I run around 32:1 to 40:1 and use the lower octane unleaded (not premium) but not E10 stuff.

I'm no guru, but I think we need pictures. Was there any other damage? Ring's welding to the piston with no other damage sounds unusual to me.
