I would suggest if there is an adjustment screw on the carb turn it open a little bit at a time till it keeps running. Left is open. If that does not work take the fuel jet out and clean it. If there is a fuel cup on the bottom of the carb remove it and clean it out as well. Try the adjusting screw first if you can. Make sure you have fresh clean gas as well.

I started this snowblower in the summer and it worked fine...both winters I've tried to use it it won't start. The first year I had it it worked very well.

So you are saying it wont run in the cold. Will it run if you left it in the house until you wanted to use it?
Are you going thru the procedure of Choking the engine ? Is there a Primer Bulb that you have to push on this machine?
I'm just saying that engines don't like the cold to begin with, just make sure you are going thru the 'Cold Start' procedure properly.

Starts but only runs for two minutes it's a toro 521 snowblower

When it dies will it restart right away or do you have to let it cool down first? It sounds like it could be the ignition module if that is the case

I have a 24" snowblower that surges after 1 minute of running, after 3-4 minutes stops and will not restart until several hours later, does the same thing over and over

This sounds like a choke issue. Do you have a choke on that engine?

The purpose of a choke is to allow for a varying air:fuel ratio depending on how hot the engine is. A cool engine needs a more rich mixture of fuel to air. Once the engine warms up, it runs best with more air. The Choke is a mechanism that allows the operator to manually adjust this mixture. Generally, the choke is closed to start a cold engine, then is opened in 2 or 3 stages as the engine warms up. As the operator, as the engine starts to run smoothly, you would actuate the choke to the next notch, changing the fuel:air ratio so more air is mixed in with the fuel. It's probably best to give the engine a few minutes to warm up while you progress through the choke stages until it's fully open providing the best mixture for operation prior to beginning to clear the snow.

If you follow that process and the engine stalls when the choke is opened, then you need to clean your carburetor.

I have a 17 year old snowblower. Sears Craftsman 3 HP single stage. It wouldn't start. I changed the spark plug and now it started but it's running very rough with excess smoke. If I press the gas...

Good to hear you got it running anyway.

Look for a choke, maybe it's just running with the choke set. Could also be that it's all gummed up from sitting, if that is the case then some running should bring it out of it by the time you've put a couple of tanks of fuel through it.

Is this a two-stroke motor? If so, be sure you have your fuel mixed correctly- go by the manufacturer's statement concerning how much oil to how much fuel, never assume that the oil bottle directions apply to your machine because they probably don't.

Good luck with it,
