Engine won't start

Hi, I have a 33cc gas scooter. The engine will not stay running. It will start for 5 seconds then die, and will not restart. It is getting good spark, I replaced spark plug also. Sometimes it will start if I throttle it in time it will stay running only at full throttle. When I stop at a stop sign it dies. It seemed like the problem started with hard starting but then working but now it is progressing worse. Please help

When in doubt clean the carburetor. You probably have a jet or passage clogged since you can keep it running if you work the throttle but it will die at idle.

Thanks, but I forgot to mention I recently put a brand new carnet author on it and that did not solve it. Any other suggestions? I'm not really sure what this could be as it runs like a champ at wot.

Sounds like you have an air leak, while it is running, spray/dribble some carb/brake parts cleaner behind the carb and along the crankcase mating surfaces, if the engine tempo changes you have found the leak and can take the appropriate action. Have a good one. Geo

I'm not sure it's an air leak? I don't think it is as it would probably start when choked. Plus if I do get it started as long as I keep the speed above idle it runs great, up until know it died when running at full throttle. Will not restart no matter what I try. I think it's trashed.

Again it has brand new carberator. After new carberator it was working then I had this problem. Could I still need to clean it out? The carb was replaced then it worked for a while now it went downhill and will not restart. Is it trashed? Starting fluid does nothing.
