The ignition timing may have been disturbed,or if it is equipped with a carburettor,the mixture setting may have been disturbed,or the carb.jet may be blocked by dirt in the fuel or the spark plug may be faulty .get all these checked first .

all mc and cycles here have spark cut out for..
not in neutral ,
clutch not held in..
bar kill switch. tripped super easy that.
kick stand kill switch.
key switch bad.
(this is generic answer.)
ICM bad, or its crank sensor bad.
blown fuses.
bad wiring
buy the service manual and study spark there.
for sure what charges up the coil to make spark.
ICM is what it there most times; ign, control module
If you have fire to the plug and the plugs gets wet with gas when you are trying to start it,, well ..if this is true, you have a compression problem.
The 3 things a internal combustion engine needs to run are.
1. Timed Spark
2. Correct fuel/air ratio
3. Good compression
If the kill switch was bad, you would not be getting fire.
being a 50cc engine it should have only 1 piston
If it is a 2 stroke , it will fire every time the piston comes to tdc
if it is a 4 stroke it has to have a timing point that excites the ignition system for every 4th stroke tdc
if the exciter receives a signal to fire the plug at the wrong time , it is getting that signal from a fault or incorrect timing
that fault can be
loose wire/s,worn unit that controls the timing ( distributor fault), loose flywheel , flywheel touching coil,incorrect timing (180 degrees out ) stator loose ,rotor loose,faulty crank position sensor
it is good practice to have a workshop manual on hand and if you don't have one go google and type in --workshop manual for 50 cc tao scooter--and see if there is a pdf version in english to download
If your 2002 Roketa 50cc scooter will not start, there are a few potential causes to consider:
Fuel issues: Make sure you have enough fuel in the tank and that the fuel is fresh. Also, check the fuel filter to ensure it's not clogged.
Air filter: A clogged air filter can restrict airflow to the engine, making it difficult to start. Check the air filter and clean or replace it if necessary.
Spark plug: A fouled or worn spark plug can prevent the engine from starting. Check the spark plug and replace it if necessary.
Battery: A weak or dead battery can prevent the engine from starting. Check the battery and charge or replace it if necessary.
Compression: Low compression can cause the engine to not start.
Starter: If the starter motor is not functioning properly, the engine will not turn over.
Choke: Make sure that the choke is working properly.
It's possible that one or more of these issues may be causing the problem. It is recommend to check the owner's manual for troubleshooting and further guidance. If the problem persist, it is best to take it to a qualified mechanic for diagnosis and repair.
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.
