That snowblower you got with it would be called a snow thrower, as it is a single stage.
If the previous owner was smart enough to use 2 smoke oil instead of motor oil, he prolly never adjusted the main jet in the carb.
Just for the heck of it, try turning the main jet 1/2 turn CCW. and see how it operates
( The main jet is the only one on top of the carb, right alongside the shaft/linkage that operates the throttle)
Let us know how it operates, it might surprise you.
