Tao tao atm50-wont start (49cc)

I'm guessing some dirt blocking the jet or a stuck float. Moving the carb around probably dislodged the dirt or jiggled the float enough to cause it to work properly again. You must have one of the newer EPA carbs. they don't want you opening those things and changing the jets but it can be done.

Sorry for the late reply. I have been busy heavily with my internship. I think you are right and as you said the carburetor has lots of "screws" which can't be opened up. I never got any moisture on my fingers when pressing on the spark plug socket. I assembled everything because of frustration. And it worked out.

So after the assembly and as the scooter started to work, It happens that when the scooter is idle overnight it would need to be started with a kick in the morning, the electric start won't work then. But after I ride it, it would work usually if there is not a big time gap after I turn off the engine. But again if it would lie idle for 4-5 hours, it requires a kick to start, does that mean my battery needs a recharge?
The battery is new as the scooter itself but I think I might have drained the battery when my scooter won't start up (the previous issue).

Check the batteries voltage in the morning and see if the voltage is low. I know its a new battery but if its dis-charging for some reason you will need to find out whats causing it. I had a old car (60 Impala) and I had to put a quick disconnect on the battery when the car was off. Had a parasitic drain. Ended up junking the car so I never found out what the problem was. Now, if the voltage is correct and it just wont turn over, hence needing to kick it, I would guess the carb is slowly flooding out over night. Could also be the petcock is not fully shutting off thats causing flooding. Last thing is to see what voltage the stator is putting out. Could be weak and not properly recharging the battery. Double check the connections to the battery for tightness and cleanliness. Finally, find the main ground on the scooter if possible and check that connection just like the battery connections. The fact that you said you pulled the carb and it started working makes me think its carb related. Float issue or petcock seeping when turned off.
