snow blower dies when under load

my snowblower runs fine till it starts to throw snow and then it loses power to the point were it wants to stall until i remove it from the snow. Once removed it resumes to full pwer and then it starts all over again once reintroduced to the snow.
the other issue i have is that it will only run under full choke. it dies immediately when i back off on the choke.

empty the existing gas and refill with premium and a fluid carb cleaner. Let it run for 20 min and that may clean the carb enough.
good luck

thank you for your response. I tried your suggestion as well as others i received yet nothing was working. i brought the blower to a small engine repair shop and much to my suprise it needs a new carb. the repair shop has 6 others in need of carbs as well. the mechanic had stated the ethanol in the fuel is destroying the carbs.
i read something a while back on this but though they were overstating the issues ethanol has been causing.
looks like the old method of shoveling will have to do until the carb comes off back order.

As far as I know, MOBIL is the only supplier of gas that does not use ethanol. My carbs gave me problems every year until I started using Mobil. A repair shop guy passed this on to me. Now I use Mobil in my snow-thrower. lawnmower, and motorcycle. Either it's true or I have just gotten very lucky for the past two years.

I had one like that, it ran nice, but no power! I finally took it into the Small Engine repair and the old guy there said it was a common thing on that series of engine. It needed a new valve - not sure which one. After it was replaced, Wow, it was a whole different machine! That must have been about 8 years ago, and it cost me about 75.00.

Probably just rebuilt the carburetor.

Exhaust valves burn out causing a leak and loss of compression which results in lack of power under load. Also a misadjusted governor would die under load

My solution was kinda dumb, forgot where the throttle dial was located, under the choke dial. Although I'd say not so intuitive where it was designed to be.

I believe there are other stations that also sell non-oxy fuel. You can probably find them online by putting in your city and non-oxy fuel. It is the only fuel to use for lawnmowers, snowblowers, that sit more than a short time, probably less than 1 month. Same goes for autos, boats, etc.
