My 50cc scooter(chinese) hesitates at full throttle, almost like it wants to stall and then it kicks back in. Could this be a problem with the carburetor valve?


Hi, Randy and the usual suspects are:
1. Inlet system air leak.
2. Enrichener valve not seated or leaking.
3. Damaged or restricted fuel tank vent system.
4. Restricted fuel supply tract.
5. Dirty or damaged air cleaner element.
6. Plugged bowl vent or overflow.
7. Worn or damaged needle or needle jet.
8. Vacuum piston assembly malfunction.
9. Loose or plugged main jets or passages.
10. Improper float level.
11. Accelerator pumps inoperative.

My scooter was running fine, then sat for a week and when i went to go start it again, it idles strong but any throttle at all and it justs bogs down. Any ideas?


It's a problem with your fuel delivery. Could be bad gas, stuck choke, some scooter carbs come with some pretty rediculous carbs that weren't engineered very well. Dirt in the bottom of carb, stuck float. Hope this helps.

I just installed a high performance air filter for my taotao 50cc scooter and it starts and idles nicely but when I go to accelerate it bogs down and dies...why is this happening


The new filter allowing more air into the motor throwing off the air to fuel mix ratio you can either adjust the carb or put the factory filter on

Scooter runs but bogs down when given throttle 2007 triton vento scooter will run bogs down when given throttle


Make sure the air box is installed and the snorkel is on the air box and that it's in good condition. They don't run well or sometimes at all beyond idle without the air box. Could also be a clogged main jet or otherwise dirty carburetor.

50cc moped runs great until full throttle then boggs down-does not do it at 1/2 or 3/4 throttle


Check for good fuel flow to carburator. If so have a qualified technician look in the carb for debris blocking the main jet. this is very common when the vehicle sits for an extended period of time.

50cc scooter lack of power from 0 to 10mph


Fuel mixture is too rich. The easiest way I adjust those is to have a friend stand in front of the scooter, holding the wheel and handlebars still while I lightly hit the throttle and at the same time, adjusting the fuel mixture screw on the carburetor slightly. applying the throttle harder while adjusting, you should feel the scooter gain or lose power.

No power


Keep changing parts until you find the solution! No, just kidding. Many will do this if they don't understand how an engine works. It sounds like it may be a hung choke. Engines need extra fuel when cold, and die when warm if they are still getting that extra fuel. Also, low oil level will give the same indication. There are many variables.

Open throttle to full. clutch wont enegage for 3 to 4 seconds


Try a new belt, it may look fine but can be polished and have no grip left.
