49.5cc JCL gas scooter will not start and SHUT OFF WHILE DRIVING 40 mPH!

I was driving when all of a sudden my scooter came to a complete stop and shut off when i was on a main road.  I pulled over and ever since, the pup wont start up.  Anyone have any ideas and if I can fix this myself instead of paying 90$ diagnostics and hrly rate to get it fixed???
I also have 1,200 miles on this and bought it only two months ago+   I recently changed the oil and gear oil and possibly put too much oil in.  I have no idea why this is not starting up.  SOMEONE PLEASE HELP!!!  Also i noticed on the left side on the rear tire there is a sticky residue dark color.  Other than that their are no obvious leaks or anything.  Please HELP ASAP!

    I have the very same issue with my 150 jcl scooter, same miles same exact issue. jcl sucks! I have only put 1150 miles on it and it has spent more time in the shop than on the road. Do not buy anything from jcl! Pure garbage!

    I'm part of the club. Exact thing with 1200km and just changed oil. This is a chineese scooter 125cc Huatian. After I changed oil, the next day took it to work and in my way back I heard some explotions from the exhaust pipe, then I was lucky that it left me there 5min from home so I didn't walk that much. Could it been worse but I also need help!
    I changed the spark plug and still the same. I checked the lines of the carburator and filter and it seems that its passing gas fine.
    I will check the spark from the cable that connects to the spark plug and I haven't checked air filters but I assume the air filter can't be that dirty since I dont really use the scooter that much.
    Any help I appreciate.

Boat was running about 20 mph and suddenly stopped. The starter would not energize. The next day the engine started ok. I believe this is an electrical problem.

sometimes car stp but are fine in a few hours. THis shows it is unreliable. Even if you get this problem fixed some other problem is bound to come up again.

Do you really need a boat. If so, then maybe you should think of getting another just to be safe.If not maybe I can help. try checking the motor maybe it needs more juice or there is something stuck in it.

My 2005 predator is making a weird grinding noise. It runs fine and goes into every gear good. It's a little slow on start up. And just when i let off the gas it makes a noise like a chain hitting the case...

It kind of sounds like ignition or timeing knock. Try running ethinol free gas if it's available or changing the octane fuel you are useing. If that doesn't help have a service tech check it out.

Good luck.

The Maxima line has problems with thermal shut off. If you have the bagless model get a new filter and that should improve the run time

Scooter will not start

I had the same problem. the drain hose on the carb is supposed to have a little valve in it. it is meant to drain your carb when you winterize, HOWEVER, they fall off and fuel runs out. Screw a small bolt into the end of the hose and bingo- it runs.
