I purchased a scooter, a tao-tao 49cc when I got my income taxes back as a means of transportation. This scooter has been the bane of my existence however. I have tried to deal with it but its latest issue, deals with my safety, its like the scooter is constantly accelerating. I start it, and its full throttle. I stop at a stop sign or stop light, full throttle. I can't back up with it because it constantly wants to go forward. How do I fix this issue.

What are the rpms at? Have you tried adjusting the idle screw?

I stop at a stop sign or stop light, full throttle. I can't back up with it because it constantly wants to go forward. How do I fix this issue. Look at the carb while you move the throttle. When you let go it should go back against the stop screw. If it's working well, make sure your stop screw isn't keeping it idled up too high. If it won't slow down when you back off the stop screw then you have a carb problem. Get a screwdriver and a can or two of carb cleaner. Take pictures of the carb on all sides so you can see how it goes back together, then take it all apart, gently, clean all of the parts and clean out the nozzles, and put it back together. It's easy and these carbs have very few parts. Just make sure to be gentle with it and put the diaphragm in the right position and don't squash it when you put the cover back on. Cleaning the carb is easier than taking a bicycle apart. Hook it back up and you should be good to go unless something is broken in it. If you have a friend who is mechanically inclined then get their help. People love to show off their skills. Just make sure they are gentle with it. Once you clean a scooter carb a couple of times you'll wonder why anyone would pay someone else to do it. |

i had an issue with my throttle sticking. the internal cable became frayed. i had to replace the throttle cable.
if your scoot is new then i would suspect the cable isn't adjusted properly. if your scoot has some miles on it then it may be time for a new cable.
or it could be something as simple as the idle screw as murkyapricot mentioned. adjust the idle while on the center stand until the rear wheel stops rotating.

I would do what scooter said,,
Just start at the top and work your way down,,remove the throttle clamp,grip,and cable and make sure the twist handle with cable guide track looks good,,then make sure the carb butterfly snaps back on its own with spring...hook cable back up and adjust it for a little bit(1/8")of play,,should be good to go....dont forget to lube the cable also...I think something is just out of adjustment or bound up.
