Up for sale is a very good condition 6421. This is a Home Depot saw I've had for a while. I planned to put a 7900 top end on it, but like a lot of my projects, I never got around to it. Tired of seeing it sitting on the shelf. Has a brand new bar and chain. Also looks like Home Depot put a brand new air filter on it. I bought 2 of these saws at the same time, might list the other one in the next few days. Runs, idles, and oils like it should. Overall pretty clean shape. I pulled all the covers off it and gave it a bit of a clean up and looked everything over. All looks great. I greased the clutch bearing and cleaned out the clutch drum. My compression tester is broken but piston looks clean and it starts easily. Looking to get $385 shipped to the lower 48. Add 3% for PayPal unless it's friends/family. I bought this saw for about $330 plus tax, so Im just trying to get my money back. Thanks Daryl
