I originally posted this in the mills forum where I was given some great info and directed to post here. Below in quotes is my original post. Saltas and Buzz Sawyer advised me to check the flywheel key which may have sheared throwing off my timing. So I tore it down today to look at the flywheel. Problem was I couldn't get the flywheel pulled. Had the puller torqued but, not having a manual, was unsure if I was doing it right when I noticed the puller gouging into the case and flywheel. I had it plenty tight and didn't want to break the flywheel. I figured it should have come off already if indeed a puller was the way to do it. Turns out it is the way but it not coming without a fight. Buzz suggested I look at the piston via the muffler, which I did. There is a decent amount of vertical banding on the piston and a small part of the ring looks deformed. It's hard to see in the pics but it's on the left side of the piston as seen through the exhaust port. I hooked up a compression gauge to see what I could see. With the piston at the bottom of the stroke I gave it one pull. The piston made 4.5 revs with a reading of 49psi. I'm thinking that is low but I'm not sure. Does anybody have any advice or ideas about 1) getting the flywheel off, 2) what should my compression be roughly and finally, is my piston/ring shot. The cylinder wall looks ok from what I can see. Any information would be much appreciated. Can't seem to upload pics, invalid file type error.
"I'm having trouble getting my saw restarted. I stalled it trying to cut too fast through a round and it now will not start. Doesn't even sound like it wants to start. Am getting fuel and am getting spark. Cleaned plug as well.(new) I choke the saw and proceed to crank it. I crank until I smell gas and upon pulling plug I find it wet with fuel. Before this happened the saw ran great and started after 10 or so pulls. Does anybody have any ideas what the problem could be? The fact it doesn't even remotely want to start, meaning no ignition of fuel at all as far as I can tell, seems strange. Any info would be appreciated. Thank you very much."
