I have a 4-stroke 2-stage blower as backup snow removal tool, but I've never really liked it. It's heavy and stubborn, you cannot operate it without sweating. Besides it gets stuck way too often by a piece of gravel getting between the impeller and its housing. We have gravel yard and road.
Now reading what you all write about light 2-stroke single stage blowers makes me want one. Too bad single stage blowers have never been popular in Finland. It may be impossible to find one here.
I have been really impressed by my single stage so far. It's handled all of our storms since I bought it, I've used it to clear up to about 10" of somewhat wet/heavy snow. That was approaching the point where the 2-stage would have been a better solution, but it's done very well.
In that storm, I DID use the 2-stage to deal with the dense, packed snow from the plows, around the mailbox. The extra power and augers torque of the 2-stage handled that better. And it was available, so I grabbed it.
It also does a better job of clearing a path through the yard. The 2-stage drives the wheels, so I just push down on the handles to raise the bucket slightly, and drive through the yard. But the single-stage does not pull itself forward if you raise the paddles off of the grass.
But it's been my go-to snowblower since I bought it. And maybe in part due to the 50:1 mix, I haven't noticed much of the oil smell sticking to me. Not needing to worry about oil changes is nice. I added a fuel shutoff, so at the end of the season, I run the carb dry, and that's it.
However, with a gravel driveway, a single-stage may not be a good solution. Ours is asphalt, so it does not matter that the rubber paddles are hitting the driveway surface, to pull the machine forward. But with gravel, it would be pulling in, and throwing, gravel as the paddles hit the ground. I think that would not work very well, unfortunately. But maybe Joe will sell you his 2-stage 2-stroke! Shipping might be expensive, though...
