What is a choke on snow blower?

The choke on a gasoline-powered snowblower engine is designed to help the motor start when it is cold. The choke works by shutting the air intake to produce a richer gas mixture in the engine’s combustion chamber.

When should you use a choke on a snowblower?

Always use the choke to start a cold engine, turning to “Full Choke.” Check your Owner’s Manual for proper choke positioning. If the temperature is above 32 degrees, priming the carburetor may flood the engine easily so try only choking the engine.

Can I use snow blower 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.

What happens if you leave choke on snowblower?

How long should you leave the choke on snowblower?

Remember the choke is closed for starting.

Close it only 1/2 or 3/4 for temps of 30 degrees or warmer. And don’t close it if you’re restarting the snowblower less than five minutes after engine shut off. But after 5 mins, close the choke and press the primer blub as you would with a normal start.

Should the choke be open or closed?

Generally, the choke should be closed for a cold start, opened for a warm start. Closing the choke, provides excess fuel which is not needed for a warm start. Excess fuel will quickly cause ‘flooding’ if cranking continues, even with a cold engine.

How long should I leave the choke on?

Can you only run with choke on?

An engine that will fire and run with the choke closed but dies when the choke is opened likely has debris at least partially blocking the fuel passages in the carburetor. In this condition the closed choke provides enough extra fuel to enter the engine to overcome the lack of fuel flowing through the other passages.

Why does my snowblower keep dying?

A clogged carburetor is most commonly caused by leaving fuel in the snowblower for a long period of time. … If the fuel cap vent is clogged, air won’t be able to enter the tank and a vacuum or “vapor lock” will occur. This stops the flow of fuel to the carburetor causing the engine to stall.

Why does my small engine only run on choke?
