A guy I work with gave me two saws today. said they wouldn't run or cut. One was a craftsman 42cc 18" bar that looked brand new with a little dust on it, wouldn't start at first so I cleaned the plug, air filter and after i figured out the crazy chain tensioner several pulls and it came to life. A coupple of carb adj's and seems to be running good. The other is a Mcollugh 3200 with 16" bar. The chain brake was on.....guess thats why it wouldn't cut. cleaned them both up and tried them on a piece of firewood I had. They cut pretty good for what they cost....FREE....FREE SAWS ARE GOOD
