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.
