Nice video borat! I liked seeing what the Craftsman can do. How are the paddles on that? I don't know the exact gap, but as I recall, I have a decent gap between my paddles and the thrower housing. Unfortunately, the Ariens paddles seem rather expensive (I think I was seeing ~$35, and it seemed like that was for *1* paddle). And they're molded into this funky shape, they're not simply flat pieces of rubber. I saw a video of how to shift your Toro paddles in their mounts to get some more life out of them. I can't do that. I wish the whole rotating paddle assembly was in a slot so that as they wore you could shift them closer to the housing. It's interesting you mention the vibration issue. I've noticed that my little HSK600 must be trying to vibrate pretty hard. You don't see the engine moving (though I could sure feel it in the handles when I tried blowing without gloves). But when I engage the paddles, the idler pulley is shaking back & forth rather violently. Everything that can be tightened is snug. I think it's the pivot for the idler that's helping to allow the movement, but I wasn't going to try and tear it apart further to check that. Just snugged everything down as best I could and left it. As the engine gets larger (and even higher RPM's; I'm only at 4600) I'd imagine the vibration issues must become more significant. It would be funny if your cranked-up engine was putting out near 10 hp; you'd have a little machine with more power than my "big" 2-stage I'd expect power won't scale up linearly with RPM, the engine presumably runs into some breathing issues as the revs climb, so I'd guess torque may drop off somewhat. But it's still going to be a lot more than stock. Do you know of other machines that use the HSK850? The Ariens SS522 uses it, not sure what else. Do the Toro CCR2000 & CCR3000 use Suzuki engines? I know those machines seem to have a good reputation.

Pretty much all the MTD/AYP/Murray/Craftsman/Yard Machines etc. used the Tecumseh two cycle engine. I've got a 2005 MTD that I picked up used/cheap just for the engine. The whole machine is like new. It's got a Tecumseh two cycle HSK850 in it. They're 139 cc engines and certainly capable of making much more than the rated 5 h.p.
I have a 140 cc Suzuki two cycle powered lawn mower that I cranked up to 6500 rpm. I found a formula to calculate horse power for two cycle engines. It took displacement, compression, rpms etc. into account and calculated the power output a various rpms. The stock engine was rated at 4.5 h.p. at 2800 rpm. When spun up to 6500 rpm, the calculations revealed close to 12 h.p. So, estimating close to 10 h.p. for a similar engine running at the same speed isn't to hard to believe. Torque is another matter. If kept in the power band, a two cycle will produce some serious torque. However, once the torque demand exceeds the engine's ability to produce it, a two cycle engine's torque output will drop off quickly. Unlike a four stroke that will slow down a bit and start to bark but keep making respectable torque until the load becomes too excessive. When that happens, the engine will just stall.

Borat, What’s the paddle shape on the Craftsman? I can’t get an exploded view for that model. Is it flat right under the chute or the smooth curve type of paddle? What are you tossing there? Most of the time the EOD big or small here is very difficult for any machine to toss. I don't think any Toro 2000 or 2450 I've had would do as well by quite a bit.

Borat, What’s the paddle shape on the Craftsman? I can’t get an exploded view for that model. Is it flat right under the chute or the smooth curve type of paddle?Yes. Flat across the center with curved edges fastened with rivets. In case you're interested, I'm using a $7.00 belt that I bought from NAPA rather than the $53.00 belt that Sears sells. Yes that's the EOD that was piled abough 18 to 20" high. Lots of slush mixed with normal snow. As you can see, I was leaning into it pretty good to keep forward momentum. It's amazing what doubling the horsepower will do for a machine's performance. Here's a pic:
