Can you only run on a full choke?
Can you only run on a full choke?
If a motorcycle or ATV only runs with the choke on, it’s because the richer “choke on” mixture is actually closer to the engine’s normal operating fuel mixture than the leaner “choke off” mixture. So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls.
Why do I have to run my mower 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. This port leads to the air space at the top of the bowl.
Why does my leaf blower only run on full choke?
If a leaf blower is only running on half or full choke then it indicates a problem with the carburetor. Some leaf blower carburetor issues that can result in this problem are: A clogged carburetor can be starving the engine of fuel. The carburetor’s air\fuel setting is too lean.
Why does my snowblower die when I turn off the choke?
Running with the choke on pulls more fuel than air. Running for that much time with the choke on, may have pulled some specks of debris into the main jet, restricting the fuel flow. Engine will run on choke as it is pulling more fuel, but die as choke is turned off.
What happens if you leave the choke on while running?
Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine. We do not recommend that any type of outdoor power equipment be operated after initial warm-up and with the choke control outside of the normal run position for longer than 5 minutes.
When to turn off choke control on outdoor power equipment?
We do not recommend that any type of outdoor power equipment be operated after initial warm-up and with the choke control outside of the normal run position for longer than 5 minutes. Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.
What happens when a choke is closed on an engine?
This contraction pulls on the choke rod and puts pressure on the choke to close completely. When the engine is started, the closed choke creates more vacuum in the engine, pulling in more fuel.
What should I do if my choke does not close?
If the choke does not close enough, turn the choke housing counter clockwise until the choke is just closed. Do not tighten the choke plate any farther by turning the housing past where the choke closes, or it will not come off soon enough.

How does the choke work on a carburetor?
When the engine is cold, the spring is contracted and pulls the choke closed. When the engine heats up the spring expands and pushes the choke rod up, opening the choke.
