Could be that the air/fuel mixture is set too lean. Needs adjustment.

Will not rev up unless you choke it?

If your engine won't rev up unless you choke it, it may indicate an issue with the fuel-air mixture, suggesting that the engine isn't getting enough fuel. The choke restricts airflow, enriching the mixture and allowing the engine to run. This could be due to a clogged fuel filter, a dirty carburetor, or other fuel delivery issues. It's advisable to check these components to resolve the problem.


4 stroke 90cc will not run with choke off unless you keep it rev up?

If a 4-stroke 90cc engine won't run without the choke on unless you keep the revs up, it likely indicates an issue with fuel delivery or air-fuel mixture. The choke enriches the mixture, compensating for a lean condition, which could be caused by a clogged fuel filter, dirty carburetor, or vacuum leaks. Additionally, check for proper ignition timing and ensure that the spark plug is in good condition. Addressing these issues should help the engine run smoothly without the choke engaged.

My Honda Shadow 600 VLX doesn't keep an idle. I have to keep the choke pulled for starting and running the engine. Can't drive as any throttle kills it. New battery. What to do?

You need to take you car to a mechanic. It is obvious you do not know what you are doing. Your battery is in the electrical system. Your choke is in the fuel system. They are separate. It is normal to pull out your choke to start your engine. It is not normal to have your choke out to run your engine. As soon as your engine starts, you should push your choke in. When you pull out your choke, you close the air going into your carb. Then you push in the choke to allow air to flow through your carb. That lets you speed up or slow down. If it won't run with the choke pushed in, try pushing the choke in slower.


When do you need to use a manual choke on a car?

If the car has fuel injection you cannot use a choke. however if the car has a carburetor without a automatic choke that is when add a manual choke cable to the carburetor choke flap. When you pull the choke flap closed it limits the air flow to the engine allowing for the engine to warm up so so it can atomize the fuel for the engine to run more efficiently. This is important in cold weather you almost always have to use a choke to start the engine.

Half choke means less air & more gas, So your Fuel to Air mixture is way off. Hope This Helps.


Where is the choke located on 1998 Ford Windstar?

There is NOT a choke on any fuel injected engine. The coolant temperature sensor does the job of what used to be the choke. When the coolant in the engine is cold, the coolant temperature sensor tells the engine control module and it determines how rich or lean to make the engine run. You can use a scanner to see if it and all the other sensors are doing the job they are meant to perform.

How do you adjust the choke on Chevy tbi 350?

That year don't HAVE a choke. Is your check engine light on ? If it is, then you need to have the engine scanned with an engine scanner to see what is going on. Problem could be the MAP sensor, coolant sensor,fuel pressure regulator. Any of these problems could be making it run RICH are LEAN. Fuel injection fuel system DID NOT USE A CHOKE.


How do you test a choke diaphragm on a tpi 1987 Chevy 350?

It does not have a choke, the computer richion's the fuel up or leans it out. The coolent sensor reads water temp, If coolent is cold then the engine will run rich just like a choke that's closed does.
