Hi everyone, In general, is there a good way to determine which model saws used the same part components - things like recoils, handles, clutch covers, carbs, etc.? I'm picking up a 021 and 024 today and I plan to part them out, but I'd like to advertise the different models that the parts would fit, in addition to the original model. For example, I often see 024 parts cross-listed as compatible with 026 saws. Any advice would be appreciated - thanks! Cheers!
