Can you help me figure out why I can't keep my scooter running?

by Daniel Sorbello
(Magnetic Island, Queensland, Australia)

Hi, name's Dan and I've got a TGB 101s scooter. 2 stroke. She is 2 years old and had to sit for round 12 months.

Has run but keeps wanting to stop. OK, here we go. It sat in storage for twelve months. Before starting, I've flushed tank with new fuel, drained fuel bowl screw(bottom of fuel bowl... some call it drain), put in new fuel and it's premium unleaded.

I put in a new filter as well. New plug. (has good spark) Cleaned exhaust pipe as well.
She runs fine for a while and dies off slowly.

Doesn't back fire at all. Goes fine on 3/4 throttle but chokes at anything more and has good compression.

I do believe I know my way around a motor, as I've been a diesel mechanic for 12 years now, but this thing is sending me silly.

I'm feeling pretty silly since I can't figure it out. I need help and I know it. Can you give an idea on what I'm missing. I'm no scooter mechanic, that's for sure.

Thank you kindly. Dan from Maggi Island

Stuart, You are much more likely to get an answer to your different question if you post it as a question here:

... rather than as a comment on an old, archived question that no one is probably going to see.

Vacuum Line
by: Jim Zeiser

Check your vacuum lines and see if they're OK, but it sounds like the carburetor has a blockage in it. I'd say a pinched fuel line but you say it runs at 3/4 throttle all right. Also try running it without the gas cap on in case the vent is clogged.

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.

ATTENTION! I have had to delete the Scooter Forum for this site, unfortunately. Despite my best efforts, I could not adequately prevent daily attacks by hackers and spammers. Even though most of their posts did not go public, they still cluttered up my website host's server space, jeopardizing my account. I appreciate everyone's contributions over the past few years and I apologize for having to do this.

Wondering why your scooter question never got posted?

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

If you "checked yes" on any of the points above, then I've deleted your post. Sorry, but I have standards. Feel free to re-submit, following the instructions I have everywhere on the site.

Also... all submissions have to be reviewed by me, and I am currently backlogged. Comments go live without approval, but still take 30 to 60 minutes to show up, so don't repost them, please.
