Not really chain saws but they do share some parts. These are two ts350 saws. I think they share some of the same parts with the 056. Maybe the ignitions. I check both saws for ignition and they both make spark. These are parts saws or make one out of two type deal. The starters look like 08s. Am I correct on the ignitions? I know the ignitions are hard to find on the 056.
