Why does engine only run with choke on?
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 does my car chug when idling?
Along with faulty spark plugs, a build-up of dirt and grime is the likely cause of cars stuttering when idle. A clogged filter or fuel injection system can starve your engine of fuel or oxygen, causing your car to judder and shake.
Is it bad to run an engine on choke?
Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine. Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.
Is it bad to drive with choke on?
It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel. If you did it for thousands of miles you’d probably end up with more deposits in the engine/exhaust, but even that is easy to sort.
Why does an engine only run on choke?
An internal combustion engine needs a precise mixture of fuel and air to run properly. When the engine is cold, it needs slightly more fuel in the fuel/air mixture for it to start, which is what the choke does. The choke increases the amount of fuel in the mixture, creating a richer mixture.
Why is my generator running with the choke open?
A clogged main jet in the carburetor, a clogged pilot jet, stale fuel, or leaky gaskets around the carburetor are the most likely culprits. Let’s dive in and quickly go over what you need to do to get your engine running with the choke open so that you can start powering your house! 1.)

Where is the choke on a pilot jet?
The pilot jet allows the gas to pass through and mix with the air while the engine is at idle (regardless of the choke being on or off). On many carburetors, it is located right below the throttle adjustment screw on the outside-top of the carburetor. There may be a plastic insert sitting on top of it.
