Awhile back I posted on my Husqvarna 51 that needed repaired. I t was a ebay say that I think I gave $180 for 5 years ago and got used perty dang hard but toasted the jug, piston and looking into about $130 in parts and not looking feasible in rebuilding (maybe later on, everything is in a 5 gal bucket) I have a tree job coming up and needing a 50cc or so replacement. Husqvarna only. 350, 359? I have not been keepin up on the models or numbers. I currently use a 137-16"b/c and a 371xp -24"b/c Needing something in between for a 18-20" b/c but light weight and not over 60cc. Prefer used.
