620P piston inspect (pics)

[toppers]

Pulled the muffler to check it out, around 15 tanks of red armor 50:1 on this. Muffler mod and that's it.

1) the marks below the rings, are they ok?

2) the gasket kind of tore at the cylinder, ok to line the old one up and put back over?

Thanks!

These are machining marks...all ok!

She is just breaking in. All looks good. I would recommend a new gasket but if ya have to use it, use this....



Just give it a day to cure/dry/harden up in a warm place before use.

Horizontal marks are good- vertical marks, smearey like or gougey are not so good.
