Why will my scooter only run on starting fluid?

by Scott
(Portsmouth, VA)

I have a 2011 TaoTao 49cc scooter.It would die shortly after I started it and die 3 or 4 more times, then quit. Did this for about a week.

So I took off the carburetor, cleaned it, put it back on and found the fuel filter was on backwards, so I put on a new one. Now the scooter won't run unless it has starting fluid in it. Any idea what is wrong with it?

Underneath the fuel tank is the fuel petcock. It has two lines, one fuel, one vacuum. Take off the fuel hose and suck on the lower, vacuum line. Gas should squirt out. If not either the petcock is bad or the tank has crud in the bottom covering the petcock opening. If it does, then hook it all up and find the drain line at the bottom of the carb. It's usually wrapped in a spring and has a screw at the bottom. Open it up and try to start the scooter. Gas should come out the hose. If not, then your float needle is stuck and needs cleaning. If gas comes out one of your carb jets is still clogged and needs cleaning.

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.
