Hello, just created my account. Decided to come down from lurking in the woods to the warm and tidy campfire that is arboristsite. I just recently purchased a nonrunning Homelite C-51 convertable drive for $10. The two main problems with it are it has no spark, and the 20" windsor bar was bent into an 'S'. Ive read as many homelite c-51 forums on here as I could, and haven't come across these questions. If there is a forum or forums that address these please point me to them: 1. The piston and head look great. If the ignition system needs replacing is it worth buying an electronic ignition conversion kit? Has anyone had trouble with them? Are they reliable? I have yet to really trouble shoot the ignition system but if I did need to buy new parts I am undecided on whether to go original, or go with the computer chip. 2. I originally bought this saw to be a small limbing saw. However, when I learned more about the this 77cc monster I figured maybe I should take advantage of it's capabilities. Homelite says these saws can take a 30" bar. I've also read on this site that these saws have lots of torque but run low rpms. Does anyone use a 30" bar on theirs? Can it handle it with the proper chain? eBay seems to have a good stock of 30" bars and 25" bars for these saws. I already have a working stihl with a 20" bar. 3. Has anyone had luck straightening a bent guide bar? I live in the Midwest on 5 acres with lots of trees and plan on volunteering on a local conservancy. We don't get huge diameter trees here but I'd rather be prepared for the unknown. That's why I'm considering the 30" bar. Any professional advice is much appreciated! Thank you!
