Changed CDI, Coil, Stator, Sparkplug now it tries to start but ...

[ErnstB]

Hello I'm Ernst

I own a Super Bee 150cc scooter with the GY6. Recently I had the bike die and it wouldn't start so I learned how to trouble shoot the Stator, Coil, CDI and spark plug to find the problem. Stator Volatage was 3 to 13VAC so there it was, Now that I have replaced the Stator I see 0.1VAC Trigger, 100VAC at the Coil and the engine cranks but it seems to "hit" like it will start on the first crank after I push the start button but not after. A couple of times while cranking it it almost started twice but didn't. I get backfire so I assume The plug is firing.

In my mind it seems like it would be a Timing issue. So I sure can use some advice on what to check.

I had no issues before it simply shut off and I ended up replacing the Stator, coil, cdi and plug.

Any ideas?
