Well, the past weekend was kinda a wash on saws again. Troubleshooted the Dolly 420 again to no avail. Still will run on idle, but not rev up properly. Partner cutoff saw crankcase showed up yesterday...a day after I left, and perhaps most sadly to me, my new to me 6421 makita is another no go. It ran on prime, but wouldn't stay running. I started pulling it apart to put my big bore on it and encountered a lot of crud in the crankcase. So i'm mixing it out with premix and fuel starts pouring out on the bench. Knew it was a seal at that point and the clutch side promptly came off. Seal fell right out and the bearing balls were all at the bottom of the race... I was super confused as there was no play in the bearing, and the piston and cylinder still had normal wear. So I am torn as to what I want to do with this one now, especially as there is some wear on the shaft where the clutch drum bearing rides that would have to be fixed. What are your guy's thoughts? Part out or do a full rebuild with a repaired crankshaft, seals, and bearings?
