I gotta 50cc qmb139 scooter with no spark going to the ignition coil how do I fix that

SOURCE: cant get my 50cc scooter to fire up-no spark. any

• Do you see spark? If not, check the side stand kill switch. It kills the engine so that you don’t start out with the side stand down. If broken or out of adjustment, it would kill the spark. Check for a broken wire at the side stand switch and coupler. Try moving the side stand kill switch by hand. If that doesn’t work then wire a jumper around the switch to bypass it.
• Is the handlebar kill switch on? Is it shorted out?
• Check the fuses.
• Check the operation of the ignition switch and all kill switches with a volt ohmmeter. Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires?
• Is the bike in neutral and the neutral light is lit up? If no neutral light, check the neutral switch and neutral switch wire on center or side casing.
• If still no spark, get CDI system and coils checked at the dealers shop.

SOURCE: i have a 50cc sunl scooter, and i cant put it bac in time

with the spark plug out and the valve cover removed; place a screwdriver into the spark plug hole; turn the crankshaft until the valves are all the way up and, not moving as the piston just starts to go down in both directions; (use the screwdriver to see this) this is TDC or, top dead center now; you should see symbols on the faces of the cam gear and, the crank gear and, two places on the chain; line up the chain symbols with the gear symbols chain symbols facing out and, install the chain.
by the way they make a kit for stripped sparkplug holes an auto parts store will have it in case you need one again.
