I will leave it alone as you suggest. Thanks for your help.
Thanks for the information. I will just run it as is until the head needs replacement. I had looked for an aftermarket head for that saw, but could only find the OEM for about $220.
I broke it trying to multitask by attaching the saw in the case to the top of my harrow when I was driving my tractor to cut up a tree and then plow firebreaks. It came off when I decided to break up a dirt pile with my loader on the way and the harrow ran over it a few times as I was going back and forth. Yes, I forgot it was on there until I looked back as I was leaving the pile. Saw seems salvageable after replacing handle, hand guard, starter assembly and a couple of other parts. To make matters worse, this was a new saw.
I also need to try and fix a narrow piece of the crankcase frame that broke just above the flywheel. Would you know what material that is? It looks like cast aluminum and I was thinking of trying to krazy glue it after cleaning it with aluminum jelly.
