How do you test an automatic choke scooter?

How do we test it?

1. Start and run the bike (fast tickover is fine) for at least 5 minutes. (
2. Switch off the engine and *quickly* remove the moped choke unit.
3. Now leave the choke for at least 20 mins to cool down and measure the distance again- distance B in the photo below.

How does an automatic choke work?

Automatically – An automatic choke uses a metal spring to open and close the choke plate. The spring is wound in a housing and attached to the choke linkage on one end. As the engine warms up, it warms the metal spring. As the spring warms, it expands, rotates, and opens the choke plate.

How do you know if your electric choke is working?

Check from red plug to ground to be sure you have power first. Your photo shows the choke in it’s cold or closed position. When you work the throttle the fast idle cam (other side of the carb) should rotate into the fast idle position. Turn the ignition on and wait a minute…..now work the throttle again.

How do you convert an automatic choke to manual?

Fitting a choke conversion kit

1. Disconnect choke. If the choke is plumbed into the cooling system, take off the radiator cap and disconnect the two hoses from the choke.
2. Remove choke unit.
3. Fit interface.
4. Fit adapter.
5. Cable anchor plate.
6. Cable spool.
7. Dash mounting.
8. Wiring up.

Should choke be open or closed when starting?

When doing a cold start, the choke should be closed to limit the amount of air going in. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up. If you are having trouble getting the car started in the morning, inspect the choke on your engine.

How do you adjust a choke pull?

On a cold engine, most preferably in the AM after sitting all night. Hit the throttle to close the choke plate. Then apply vacuum to the choke pull off. and adjust the screw until there is 1/8th inch between the choke plate and the carb body.

How do you start an automatic choke car?

If the choke is an automatic type, one or two strokes on the gas pedal will set it. Assuming the ignition is up to par you can now hit the starter. With your foot pushing the gas pedal down about 1/2 of the way, crank the engine until it fires. It will usually start running, but rather rough.

How long should electric choke stay on?

At 5°-10°C (41°-50°F), the choke plate should be fully open in about ten minutes. Check for bent choke linkage and a defective thermostat cap. And ensure the fast idle cam (screw) is properly set.

Where do you connect electric choke wire?

For electric choke hookup, attach the bayonet end of the long electrical lead supplied to the positive terminal on the choke cap. The other end must be connected to an ignition activated 12-volt source. The distributor side of the ignition coil is NOT a 12- volt source. It is a 7-9-volt source after cranking.

What does a manual choke do?

A manual choke is a mechanical device that links a retractable knob in the driver’s compartment, via a cable, to a metal plate inside the carburetor. The metal plate moves to increase or decrease the amount of intake air in order to provide the optimum fuel mixture for the engine.

How to test a choke on a scooter?

And also check if the piston is retracted after an hour of cool-down or so. Ah, and as first test, check if the choke gets warm. To apply power, either take a ride or connect the choke directly to the battery. But note that the choke draws about 1A, which can drain a small 7 not fully charged / weak scooter battery.

How do you measure the length of a choke?

The needle should be clearly visible. Measure the overall length of the choke from end-to-end, including the very tip of the needle. Now connect the choke’s electrical leads to a 12v power source. Black is negative. Wait 5-10 minutes and re-measure. The needle should have extended. The overall length should be approximately 3mm more than before.

How do you remove a choke from a 150cc buggy?

Measure the overall length of the choke from end-to-end, including the very tip of the needle. Now connect the choke’s electrical leads to a 12v power source. Black is negative. Wait 5-10 minutes and re-measure. The needle should have extended. The overall length should be approximately 3mm more than before. How do I remove the choke on the 150.

Where is the needle on a carburetor choke?

Remove choke assembly from the choke holder on the side of the carburetor. The needle should be clearly visible. Measure the overall length of the choke from end-to-end, including the very tip of the needle. Now connect the choke’s electrical leads to a 12v power source. Black is negative. Wait 5-10 minutes and re-measure.
