Why wont my engine run without choke?
Why would the engine only run while the choke is on or with repeated manual priming? 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.
Why does my machine only run on choke?
What you have is an overly lean air/fuel mixture being provided to the engine. Using the choke richens the mixture allowing the engine to run. More then likely your carburetor needs to be rebuilt. There's probably a bit of dirt stuck in a jet or the float is stuck.
Why does my engine cut out when I take the choke off?
Bad fuel(install fresh good fuel), possible weak fuel pump(if equipped), pinched/collapsing fuel hose, clogged fuel filter(unhook spark plugs, remove fuel line at carb. and check for fuel flow, will have to crank engine if equipped with pump), clogged vent hole gas cap(try running with cap loose or removed), carb.
What would cause a generator to start but not stay running?
The carburetor might be clogged or have bad fuel in the float bowl. If old fuel was left in the small engine for a long time, some of the volatile ingredients may have evaporated, leaving a thicker, stickier product that is more like varnish or shellac.
Why does my generator only run on half choke?
Yes, you need to clean the jet out, or try to replace it and see if either of those helps. Yes choke is blocking off the air to richen the mixture for starting. It needs to be part on so the engine can get the fuel it needs. The engine is not getting enough fuel with the choke all the way off.
What happens if choke is always on?
If you forget to turn off the choke after starting the engine, it will continue to run rich, meaning there will be more fuel and less air. This can result in the engine operating inefficiently, consuming more fuel than necessary, producing excessive exhaust emissions, and even causing the spark plugs to foul.
How do you fix a generator choke?
Pulling the choke lever provides proper fuel-starting mixture when the engine is cold. When attempting to start a cold engine, pull the choke lever outward to close. Slowly return the choke to the open position as the engine warms. Leave the choke in the OFF/OPEN position when starting or restarting a warm engine.
How do you adjust a generator choke?
A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine.
Why do engines need choke to start?
Try unplugging loads and running the generator with less applied. Is the fuel shut-off valve turned on? Without the fuel valve turned completely on, gas cannot get to the engine for proper function. If the fuel valve is on, check the fuel filter and fuel line for clogs.
Does a choke cut off air or fuel?
The problem could be caused by a few things like the carburetor, fuel filter, kinked fuel line, or a weak gas pump. It can also be a carburetor gasket. The most common issue with a generator that is occasionally used, where some gas is kept in the tank, is varnish deposit in the carburetor.
How do you fix a generator that keeps shutting off?
No engine is made to run on half choke. If you are running on half choke, you are compensating for lack of fuel due to a most likely dirty or gummed up carb. You will eventually foul spark plug running on half choke for a period of time. The brass nut holding the carb bowl on should be the main jet on that.
How do I keep my generator running?
Turn choke on
This makes it easier for the engine to start running.
Why does my generator keep going out?
Brain death will occur in 4 to 5 minutes, if strangulation persists.
Is it bad to run an engine on half choke?
Here's your answer: Yes, it absolutely does. leaving the choke closed after the engine has warmed up results in increased fuel consumption. This setting creates an over-rich fuel mixture, causing the engine to run inefficiently.

In summer, about half a minute on full choke and a minute on half choke. In winter, one to two minutes on full choke and the same on half choke. You will know from the feel of the engine if you don't have enough choke.
Do you start a generator on choke?
When the carburetor is clogging up, it makes the engine start to run rough, sputter, and shut down. Fuel may sputter up and soak the spark plug(s) stopping the residential backup generator from even starting. Luckily, cleaning out the carburetor fixes most residential generator performance issues.
How long is too long for a choke?
As the outside temperatures rise, it is possible for the fuel tank to pressurize or actually become vacuum sealed due to the gas cap failing to check the pressure or vacuum.
What happens if you leave the choke closed?
Restricting the incoming air creates a lower throat pressure and helps the carb suck more fuel into the throat. Between less air and more fuel, you get a rich fuel mixture that helps the engine get started. Once it has warmed up a bit, the choke is opened and the mixture returns to normal.
How long should I leave the choke on for?
The engine performs better with the right fuel mixture, so the choke should be slowly backed off as the engine warms. Once it reaches, operating temperature, the fuel and air mixture is regulated by the throttle plate and carburetor. Some carburetors have automatic chokes that ease the choke off as the engine warms up.
Why does my generator keep sputtering?
The automatic choke includes a choke valve movable between a fully closed position and a fully open position, a temperature sensor coupled to the engine and operable to provide a temperature signal indicative of a temperature of the engine, and a motor connected to the choke valve and operable to move the choke valve ...
Why does my generator shut off after 30 minutes?
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.
How do you adjust a choke valve?
If the choke valve stays in the closed position longer than necessary, the engine will continue running rich. More gasoline goes unburned, wasting fuel and increasing emissions. Running rich can also reduce performance and wear out parts faster, increasing the risk of a more severe issue.
How does a generator choke work?
No. A choke reduces the amount of air, keeping the fuel amount the same, making the mixture richer. An enrichener keeps the air the same, but increases the amount of fuel, making the mixture richer. Two different methods to do the same thing.
What controls the choke?
Components of carburetors usually include a storage chamber for liquid fuel, a choke, an idling (or slow-running) jet, a main jet, a venturi-shaped air-flow restriction, and an accelerator pump.
What controls the automatic choke?
Chokes restricts the air to the engine through the carb to richen the mixture for start up. More modern carbs have an enrichner that opens a fuel passage to richen the mixture. As the engine warms up it will vaporize fuel better and now the extra fuel is not needed.
What happens if you leave the choke on overnight?
A fault in the exhaust system can cause a generator to fail after a few minutes due to a buildup of exhaust causing a fault in the noxious emission sensors. This is a critical issue that needs to be dealt with by a professional.

Fuel may sputter up and soak the spark plug(s) stopping the residential backup generator from even starting. Luckily, cleaning out the carburetor fixes most residential generator performance issues. The sure-fire way to clean out the carburetor is to disassemble it, clean each part, and reassemble it again.
Does a choke cut off air or fuel?
If your generator has a lean fuel-to-air ratio, it will cause slow combustion. During slow combustion, the combustion process cannot keep up with the air and fuel mixing in the combustion chamber. When this happens, and the exhaust valve isn't open, it leads to valve overlap, and the generator will backfire.
What happens if you choke too hard?
