Long story short. Scored piston and cylinder, due to straight gas, usual stuff. Changed the piston, cleaned cylinder, according to dealer also bearings and seals were shot, so changed these too. Now, she has 90PSI compression and starts after 10th pull. Low compression can be felt pulling the starter cord also. Then she idles forever but if I push the throttle it revs and then dies. What's confusing is that it idles normally with that compression. Usually low compression means no idle, they start but then die immediately. Can it be that there is just enough power for idling not for cutting or maybe I have to check the fuel line before tearing everything apart again. Tearing apart is not hard but takes time again which we all know is a rare commodity. Parts are all chinese, piston/rings RedBarn. Meteor sadly doesn't have newer version piston for MS291.
I have my suspicions about the cylinder also, maybe I went overboard with sanding and the piston/rings are not tight anymore. Sorry for my weird English, I'm not a native speaker.
So the main question, have you seen well idling low comp saw.
