Why won't my 250 Tank scooter idle consistently?

by Bob
(Downingtown, PA)

I had problems starting the scooter periodically and then discovered that the fuel filter was leaking. I replaced it and now it will not idle consistently. If I give it a little throttle it will start up.

Once I get it started it will not idle without throttle applied. I adjusted the idle multiple times but it would not run at a consistent rpm... sometimes it will run up to 5,000 and I have to back it down. When I back it down even a little it won't idle. This scooter is two years old but only has 200 miles on it.

Thanks but it wasn't the fuel. I adjusted the valves,cleaned the carb, replaced the fuel lines and filters, the carbon vacuum lines and replaced a bad coil. It starts right up now but hogs down at one quarter throttle. I need to adjust the diaphragm needle in the carb because it seems to run rich. The air fuel screw adjustments would not clear this up now I think it'll be roadworthy after that......just in time for the first snow.

poor idle

With it being two years old and only having 200 miles on it I would say that your gas is bad and that your carb is totaly gummed up. The jet that sprays gas into the carb has a really tiny hole and it doesn't take much gunk to clog it up. You may need to get your air cleaner off and spray carb cleaner into it to begin with but you may also be able to get away with a can of fresh gas with Sea Foam Gas Additive mixed in. Sea Foam, even though the name is a big strange, is a must have for scooter owners because it really works on those little engines. Good luck and I really hope this helps.

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.
