Why does my scooter stop when trying to rev?

by Tyler
(Gresham, Oregon)

I don't know the exact model of my scooter. I got it from my friend and it's been sitting in his garage for a few years.

I can get the motor to start, however once I try to rev it (twist the handle to start moving) the motor just dies. I've tried letting the motor warm up for 2-10 mins but the problem persists.

why your scooter stops
by: Anonymous

You need to adjust the fuel air mixtue. This is done by turning the small brass screw locater on the left side of the carb. Turn this screw in until it is snug but not too tight. Now turn the screw counter clockwise one and one half turns. This is usually the factory setting.

Try giving the throttle a twist and see what happens, if it still bogs down and dies turn the screw slightly more to the left. Try the throttle again.


The idle speed screw on the right side of the carb should be set as low as possible so that the engine is running on the idle jet only. Keep playing with the air fuel mixture screw until your scooter runs properly.

add to vaccuum line
a. Fuel pump.
b. Fuel filter.
c. Carb. needs cleaning.
Add Sea Foam in the tank and let it run at idle until it reaches carb. This stuff work real well.

Vacuum line is off or broken. The scoot goes off in the fuel mixture when you open the throttle and dies. Look for hoses off at the carb or intake manifold

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Read our review or go right to Amazon.com to buy this highly recommended Battery Tender Jr NOW...

Wondering why your scooter question never got posted?

Chances are, there is a good reason. Did you...
