You may need to adjust the fuel/air ratio. There is a small screw under the pull starter facing horizontally (its behind the plastic air filter cover, but accessable) adjust either clockwise or counter clockwise in small increments and give it gas and see if it dies or boggs down. Also check that spark plug is clean and not fouled, and air filter is clean and oiled.

SOURCE: I start the scooter up

Condensation from inside the gas tank has probably made it's way into the carburetor. There is probably a drain screw on the carb float bowl. Drain the bowl, let it refill with gas, then see if the problem has gone away. Also, it may be time for a new spark plug. If none of that works, remove the carb then remove th float bowl from the carb and clean the carb with spray carb cleaner. Spray into every little hole in the carb. Below is a generic diagram. Please rate my answer. Thanks! tombones49_70.gif

How do i fix a throttle on a sterling sapphire mobility scooter

The Sterling Sapphire is not sold in the USA so, you may want to verify this information with a local technician however; 7 flashes or beeps is commonly a throttle issue. When the problem starts and you have been driving for awhile, ensure the throttle lever is in the stop position, turn off scooter, wait 10 seconds and turn scooter back on. If that does not clear your problem: There should be two set screws (very small) that you can tighten with an allen wrench on the throttle lever. Make sure those are tight.

If this is a continuous problem, you may need a new throttle potentiometer.

Znen 125t-f scooter starts but wont go

Make sure the airbox and filter are in place and securely attached to the carburetor. Check that the carburetor is secure in the intake. Make sure no vacuum hoses are missing or ports are left uncapped. Verify that the spark plug cap, ignition coil connectors, stator connections, and grounds are not loose. The fuel lines/filter could be partially clogged. The float level (in the carb) could be set too low. The carburetor may need to be cleaned. Carburetor jetting or adjustments could be off.

I have a lynx L-3 scooter and when i try to get it to go. after i turn it on .i let it set for a few menites and the push on the throttle control lever and it want move. if you will push it a little with...

Your scooter has an auto lockout timer. After it sets with the key on, for a determined amount of time, ( all scooters times are different) it will lock out and you have to turn the key to the off position for 9 seconds and then turn it back on. A good idea is to turn the key off when not moving.
When you turn the scooter on just wait 9 secnd before pushing the throttle.

Good Luck

I have a gogo scooter it bleeps once than cuts out I have to turn it off and back on for it to move

probably a dead battery or a bad battery will move you till the controller gets to a threshold voltage then it beeps and stops , testing this is easy turn on the scooter adjust the speed control to the lowest setting then start riding the scooter at full throttle then start turning up the speed controller if that produces the problem then the batteries need charged or replaced

Throttle does not cut off when released. Scooter keeps creeping f

ok, right the throttle lever has moved round slightly,

Look under the throttle lever where it connects to a stem, this stem should have a cross slot on it , you need to undo the throttle lever, two allen bolts inserted in the lever, move the cross head with a screw driver while holding the throttle lever still, you will need to experiment but it quite easy to sort, the cross slot should be nearly centre when looking under the throttle lever.

Hope that makes sense.

Alini pocket quad wont move

Have a look at the choke lever. From the starting position, move the lever about 10mm up until you hear a slight click. If not then the clutch plates are not responding to the throttle input. Any lawnmower repair garage will be able to help you more. The 2 stroke works on centrifugal clutch, that is the clutch plates move outwards when throttle lever is pulled. It is a bugger to start. I've got blisters on blisters from the pull cord. My son is 10 and he may well be a little big for his but when it goes, it is fast enough to start kids off with motor bikes. Hope it helps.
