The fellow I talked to the other day at Fastenal about getting the 9/16" rod never called me back so I found a 1/2" rod and make it out of that . Of course once it was on the saw I needed to try the saw out.To be honest I was apprehensive the first time that 20" blade started to spin ! OK the dry run was over then headed over to the garden where I had some small branches that fell from the trees that are a pain to cut with the chain saw . Even though the blade should be sharpened it did quick work on most except for the dried 4" + ones . The biggest problem is the carb needs adjusting/cleaning wouldn't keep steady speed.
