Just cleaned the spark plug and air filter. Now just sitting on the stand and putting it on full throttle it cuts in and out. Like goes full power then cuts down then picks back up.
The carb. may need cleaning/adjusting. If it is jumping around rpm's you may also have a vacuum leak somewhere. If your intake filter was clogged the scoot will try to pull air elsewhere. This may have sucked out a worn seal, or the coupler that mounts the carb to the engine. Sounds like your scoot needs a through going over to know what is happening. Do you have a scooter shop anywhere near you. Some shops will "hook you up" if you mention the forum, and "advertise" for them.
Jpreston has a running scoot, and he still wonders what the hoke under the seat is for.
