First question that comes to mind, what RPM is the engine running at?

I have no idea - I start it - it runs. There is no throttle to adjust.

Perhaps checking the rpm would be a good idea.
Does it also reverse excessively fast?

Also, you could tilt the machine into the service position (drain fuel first), remove the bottom pan and try visually adusting, move the friction drive wheel as close to center on the drive plate as posible.
Checking the RPM would still be my first step, as if the engine is over reving, there could be issues.

With only 2 reverse speeds I don't have a much of an expectation for how slow it goes. The snowblower is now 4 hours away and I don't have the ability to check the RPM.. From my ear it sounds acceptable, but fully recognize that is not a scientific analysis. Let's say it was running faster than whatever is ideal, what would I then adjust?

There would/should be some form of idle adjustment on the Carb.
