Good morning folks. I recently picked up another Pioneer farmsaw 2 as a parts saw for my other one. The guy I bought it from said it had no spark. I figured easy coil or plug fix. Turns out it does fire up but only choked and dies after a couple seconds. Carb kit would be next I figured. I pulled the muffler and plug out and the piston has a lot of carbon buildup at the top and a lot of carbon scoring all around it.  The ring is not froze up though. The compression does seem low compared to my other saw when pulling the cords. I am planning to give the p and c a good cleaning and put a new ring on the piston. Im new to pulling the jug and pistons out of saws so my questions are. Do I have to have the cylinder crosshatched or can I put it back together as is. Ive heard some say yes and some say no. Can anyone look at the pic and tell if the cylinder looks glazed? Shining a light inside it I don’t really see any amber coloration. Any help would be greatly appreciated!
