I took my Mathes Cooler over to my pal Mr. Doggity. He's a lot handier than I am. He took it all apart, took out the motor, cleaned up, and re-oiled it, then cleaned up the rest of the unit, and it fired right up. Says it's running like new and I can come pick it up. Pic of the cleaned up item attached:
Just cost me a case of beer.
Pretty good deal.
Thanks Mr. Doggity!
What are friends for?!!
