I have a sunny 50cc moped.. i try startin it.. it'll make the sound it wants too start.. but it just wont do it.i've changed to sparkplug.. and got a new carb.. any suggestion??..

Change the plug if spark still faint then check plug leads & coil.

What kind of cleaner did you put in the tank? Then you ran the unit with the cleaner in the tank? This is a two-stroke unit; correct?
Hearing that you put cleaner in the tank and that it now turns over faster than normal leads me to think that you have done internal damage to the motor.
Perform a compression test. Good compression is 140 to 160 psi. Anything below 90 psi means the motor needs to be rebuilt with new cylinder, piston and rings, crank bearings and seals, etc.

Hi, Check fuel tank that it has fuel. Check sparkplug and/or replace it. Make sure engine has spark when cranking it over. Good luck.

check all tubes around the carburattor.

Make sure the fuel tank is filled, the key is on, stat peddling. It should start.

i have a 49.50cc beron motorscooter and when i received the scooter it had spark but now there is not any spark bought new sparkplug and new coil still no spark

the gapping is standard you can u a match book and if it slides between the gap easy it is fine if it wont goo in the gap it needs to be gapped more if there is alot of space between it, it needs to be closed up some.

change rollers in the variator

Check the whole system over an see if evory thing is fastened securley,make shure that no two wires are toucing!
