If you mean definable scratches, that say you can catch your finger nail on then no, it is not good. How not good depends on how deep they are. Did you perchance do a compression test before you tore it down?

I have that saw. mine runs like a top. How many times do you push the primer button? If you got the jig off hone it. clean the piston dome, ring groove and ring. Knock off all the carb in the dome of the head.

Once you flood the comb chamber it won't hit till the spark plug becomes unsaturated. The best way to clear comb chamber is to remove the plug wash if off with carb. cleaner and pull the rope to clear the comb chamber. That saw should start right up with 3 or 4 primer push, full choke, trigger locked in half throttle providing the spark plug is OK and you got good compression.

If the cylinder is scored is the piston not equally as scored? Even if the cylinder is honed enough to make it Ok the piston skirt seal is necessary for adequate base compression in a two stroke engine. Normally when a saw is salvaged from a seizure a new piston is installed.

BTW, what caused the scoring? Has that condition been corrected?

no i didn't do a compression test.yes you can catch you'r finger nail on the scratches.used some gas my friend had with boat motor 2 cycle oil mixed with the gas.it was not ash free.both cylinder and piston are scratch with the same pattern.

Sounds like you need a new p&c (piston and cylinder).
