Do I Need to Adjust My Carburetor?

by Luke
(Somewhere)

I have 50 miles on my 50cc scooter and all of a sudden it seems like you you grab too much throttle; it peters out. It's like it's not getting any gas. Where should the air fuel mixture screw be at? Right now it is two full turns out. Please help.

Vacuum line

I had the same problem with mine. There is a small nipple on the head of the engine. The hose that connects to it runs to the air box. Make sure it is connected.

Idle Adjustment
by: Jim Zeiser

No, your idle adjustment doesn't have an effect on that. I would start looking for a twisted vacuum line or kinked fuel line which would cause it to starve out. At worst you're only a half turn off in the idle adjustment and it shouldn't make it run that bad.

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.
