Picked up a running Honda HRR2164TDA today on Marketplace for $20. Manufactured sometime around 2007 I believe. It had barely any oil in it and a very old worn out Torch spark plug. The self-propelled feature doesn't work which is actually fine because it's just for my son to use and I'd actually rather not have him use that feature. I think it's safer for him to just push. Went ahead and removed the belt, changed oil, new NGK spark plug, and air filter. I already had all the stuff I needed as I keep spares around for my other Honda stuff. Deck was already pretty clean and the blade was in good shape. Not certain but I think the deck is aluminum. Runs like new and seems like it has plenty of life left. I figure if he breaks this one, I don't care. He was pretty happy to cut a few rows with it today.
