I picked up a Stihl MS290 from a local shop yesterday. The plastic is in excellent condition but the saw had no compression. I tore it completely down to find that the rings were in pieces.
When I used to work on small 4 cycle engines I was told that excessive use of starter fluid can crack the rings this way. Could starter fluid be the cause of the same problem in a 2 cycle engine?
The saws in great shape otherwise including the inside of the cylinder. I'm going to put a new piston and rings in it along with cank seals and a carb kit. She ought to be good as new soon.
