1. I determined the motor itself was fine by removing the side cover and bar/blade and running the chainsaw.
2. I removed the old side cover which appeared to have excessive wear in a few areas.
3. I put on the bar and chain and fitted the new cover in place.
4. I adjusted the tightness of the blade and made sure the cha in oil reservoir was full.
5. I started the chainsaw and it ran normally.

Simply replaced the parts. I have ordered parts from you before for other saw repairs that weren\'t quite as easy as these. But these repairs were easy because I was able to get exactly what I needed from you. No telling how long it would have taken me to go out on my own looking for these parts. Your website and parts diagrams make i t easy to do repairs even if you\'re not \"mechanically inclined\".

Thoroughly cleaned saw. Replaced chain, properly adjusted chain tensioner, put on clutch/chain break cover and put on new flange nuts. Saw, 1983 Husqvarna Rancher 50 now works fine. Thanks for help with identifying and confirming needed parts.
