I just had one come in for service on an early 1960s Ariens. I gave it a tune-up, cleaned and adjusted the carb and it runs like brand new. This ~50 year old machine starts first pull and runs with no smoke. Granted, Tecumseh engines don't have the best reputation, but I've seen many of these old snow engines still around running great.
Anybody have one they'd like to share? I meant to get pics of this one but I forgot until after the owner had picked it up. It was probably the oldest Snow King engine I had ever seen. It had a primer that you had to push against the carb to block of the air inlet and suck in the fuel as you slowly cranked the engine a few times. It also had a 1" screw on canister muffler.
Since this is BITOG, I filled it with PP 5w30.
