Changed all the electronic components and it still won't start it act like
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
