Thanks Adw, yes pin’s still in tact. Have found a meteor piston online that looks ideal. Rebuilt the saw not that long ago, recycled pot and piston, but put a new crank in. Will double check the rod spec. Cheers

Adw, would prefer to put a meteor piston in a hyway pot, but as it comes as a set would probs gamble with hyway. Do you mean the pin that prevents piston ring from spinning? Everything thing seems to be accounted for. cheers for ur input ?

Thanks for input guys. Bill, the backup plan was to run a meteor piston in it, so glad u’ve seconded that idea. Adw, I’ve heard that below exhaust port is not a huge issue as compression comes in to play above it. I was thinking that as long as it’s smooth and like you say no transfer then should be ok. Was just a bit worried the plating/ nicosil/ chrome had been taken off and would cause an issue? alternative would be a Hyway cylinder assembly, write up seems to be positive, be interesting to hear what people think. cheers folks

After loss of compression, took the pot off my 357xp to find piston ring in 2 pieces. Piston is scored, and the cylinder had a couple of small but deep scratches below the exhaust port. Everything else is good and clean. ive since ground/sanded out the scratches, but this has taken off a small amount of plating below exhaust port. I’m just wandering if this is serviceable, or a def no no. Any advice appreciated. I’ll try and put some photos up. Cheers
