MTD/YardMachine 2-Stage won't start

Soooo....my girlfriends mom has an MTD 2-stage blower (Model #31BS63BD516) that has been sitting for several years with gas in it that was completely varnished (very yellow). I've drained it out through the bottom of the carb. I put some "fuel system" cleaner in the tank (because that's all I could get on new years day at the gas station and I really wanted to try and get it running for her) and let it sit for a couple of hours and then drained that out and put fresh gas in. I can get it to start if I spray starting fluid into the carb but it won't stay running. Also, I notice some oil coming out of the exhaust.

I've pulled the spark plug and cleaned it up with some sandpaper and it seems to be sparking well.

So, it would seem to me that its not getting adequate fuel since I can get it to start with starting fluid but it won't keep running. I would assume that the fuel system is all gunked up from the old gas that was in it.

What should I do here? I'm having trouble finding much info online about this model as it looks like it's a model that was specific to sell at Canadian Tire Company (she's canadian). Its a PowerMore engine.

Suggestions?

Thanks!
Chris

I'm having a heck of a time trying to figure out what the right P/N is for the carb. I have found lots of ones on Jack's Small engine and RepairClinic and even Amazon, but I'm not sure theyre the right ones. They list lots of different carbs.

On the carb or the snowblower? The Model # for the blower is in my original post. I haven't pulled the old carb yet. I even called the people at the MTD Parts website and they could only refer me to an authorized dealer in my area...ugh.

Im sure youtube has a video on cleaning a powermore carb. I've never replaced an entire carburetor because of gummed up old gas. Its absolutely possible to clean it throughly and reinstall without replacing any parts. Id atleast give it a shot.
