Think I got me a hot rod today. A neighbor sold his house and was liquidating. Seems like everything works perfect except the auger belt is too small. Doesn't stop rotating when you release the handle. Also one shoe needs replacing. Other than that I am pretty stoked with it. Need to do the paddle mod also. If anyone in the Sonora CA area is looking for an excellent shape 8/24 electric start 924082 pm me as its little brother is now for sale. Last pic is the one for sale.

Even with a Tecumseh 8hp, it doesn't bog down in heavy snow at all. So, GX390 is overkilled for that snow blower, unless you increase its snow output, and a larger belt.

A Honda GX390 13hp is nuts on a 24". That would be nuts on a 26" and perfectly suitable on a 32".

So some of you think I should sell the GX 390 and put a stock 8 hp motor back on it? Really? Whats the downside of more power? All my blowers get the the impeller mod including my my 924082 with the stock 8 hp motor. The 390 is on a (924050) Thanks DB. I found some of your posts last night and will be reading the rest of your posts soon. I watched some you tube videos of big motors on blowers and they were very impressive. Are you wishing you had a lot less hp? Seems like with the right pulley you could throw large amounts of snow a long ways. I don't see any downside to more power.

8hp is all you need to be powerful on a 24". Put the 13hp on another blower or sell it. Many put the 208cc Predator on a 24", even on larger up to 32" though IMO that's way too large, 26" would be the max.

The impeller mod doesn't seem to bog down an engine, so it doesn't matter. The impeller blades on old ariens are wide so they scoop up a lot of snow. If you go with a bigger pulley, the belt might not be able to handle it. It will have short life-span.

You should keep the Honda engine. It's a better engine and ready to rock and roll whenever you want it.
I don't think many people interested in GX390 unless it is cheap.

I have the Predator 208 on an old Murray Craftsman 5/24 with tracks. Its a great little machine now that it has the much more powerful motor lol

there is really nothing wrong with a 8hp on a 24" machine. power to size wise the 8hp is a pretty good. definitely better than something like a 5hp which is under powered. you do also see some 24" machine with a 10hp machine but most machine just run a 8hp because it does the job pretty good. a 13hp honda is really overkill.

Typically, too big an engine results in excessive fuel use, and may carbon up, since it is running at such a low load that it can never get up to temp. Couple that with possible balance issues, and more wear and tear on the chassis due to the weight, and I don't really see an upside. GX are great engines, you just need the right blower under it . . . Myself, I doubt I would put one on a 24" even if free . . .

I'd keep the GX390. First of all... it's really 11.7 horsepower and not 13hp, with 19.5 ft-lbs of torque. Everyone was guilty of fudging horsepower numbers back in the day.

There's a handful of folks here running GX340s/GX390s on snowblowers: @legarem @FredGraham @Jean-Michel Dufour @bcjm etc etc

There's one other member whose name I can't recall at the moment, he had some youtube videos posted of his snowblower in action.

My only problems with my GX390 924050 snowblower:

1) Mine could use an impeller kit as I've had the chute clog in wet snow.
2) I don't get to use it very often because there's always a snowblower or two ahead of it in the rotation that I'm trying to flip, and a good proper storm in my area has been rare lately.

There is no such thing as too much HP. a 13hp or Predator 420 sounds just about right. Apparently you guys have every tried to move what was left behind by the snowblower here in the upper midwest? you should try it sometime- there is no such thing when it comes to too much HP

I feel like the belts on your snow blower would likely disagree with your statement. They can only move so much power before they just give up and fail.
