Why does my snowblower only run with choke on?
If you have a choke lever separate from the throttle and the engine only stays running when choked, then your carburetor has a fuel blockage causing it to be too lean(not enough fuel). The only way to balance the fuel air mixture is to restrict the air by choking it. That’s why it runs better on choke.
Can I run snowblower with choke on?
If your snow blower is cold, you’ll want to pull out or turn on the choke while you’re starting it. This closes off the air supply to your carburetor, which makes for a much richer fuel mixture. If your snow blower is stored in a heated garage and is warm enough, you should not use the choke.
Why does my snowblower start then shut off?
The carburetor might be clogged. A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time. This stops the flow of fuel to the carburetor causing the engine to stall. To determine if the fuel cap vent is clogged, try slightly loosening the cap and then starting the engine.
Why does my snow blower only run when on full choke?

Why does my lawn mower run with the choke on?
If your lawnmower will start and run with the choke on but dies when the choke is turned off, it may have a problem with the carburetor. The carburetor brings air and fuel together and mixes them in the perfect ratio for combustion before they enter the engine.
What happens if you leave the choke on during engine warm up?
Solution An engine that requires the choking ( partial or full ) after initial engine warm up is an indication that the engine fuel air mixture system is out of adjustment. Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine.
