I have a 50cc 4 stroke chinese scooter. At the moment it will start and stop after a few seconds. Ihave checked for spark and fuel in carb all ok. The spark plug is not wet even after trying to start it as if to flood it. Float level ok jets clear. The only thing that looks odd is the throtle pin seems to be not tapered properly

Question edited heavily and to add maker.
Question moved from Cars and Trucks to model category.
This is a 4 stroke engine and gasoline doesn't freeze, only diesel goes syrupy. The most likely reason would have been condensation and damp causing the spark to short out. Another possibility might be old gasoline?
Engines only need three things to run
Fresh clean fuel.
A spark at the right time.
Compression
When was it last serviced, spark plug checked and gapped? Spray some WD40 on electrics.
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
