The pouring fuel down the vacuum tube solution didn't work either.

Time to eliminate some of these possibilities. The spark plug DOES fire. My finger IS forced out of the spark plug hole when cranking.Now, what are the remaining possibilities?

Yes, there is a spark when I hold the plug onto the motor. One of the parts that was new right BEFORE the attempted variator-adjust was the plug so it is not too short etc. The other info about the cam etc is beyond my present comprehension level. If fuel is in the line right before the carb and there is a spark, what's in the small space between them...the throttle or whatever opens and the fuel is s'posed to go to where the plug is firing etc. If there is suction I don't get what could be stopping the ignition.

I tried the old CDI but it didn't start. The variator did turn very little and then I tightened the stopper a little more but not with excessive force.I couldn't remove the bolt because I only had a crescent wrench or whatever and I may have been turning it the wrong way. Does it unscrew by turning it counterclockwise or clockwise?

It didn't start with the old CDI either. How do I diagnose and deal with the timing issue? My intuition says the spark is not igniting the fuel...duh. Would the timing affect that to the degree of absolutely nothing happening when the starter revs?

It has a new plug. I will try your suggestions from the current response then get back to you. Per the initial post, it was running fine, then the next day, I removed the new plug and used a piston stop to remove the variator for checking the condition of the weights. From then on, it hasn't started. In the interim, everything related to starting is new, CDI, plug, battery, magneto, solenoid, petcock, etc. It has to be something that happened after the variator check and before the new stuff was added since the new parts have not seemed to make a difference.Thanks

The picture looks same as mine...hoses are hooked up correctly and there is a spark but the scooter will still not start. What other possible problems could there be?

I went to a YouTube video so my question is already answered but the scooter still won't start even though there's a spark and fuel in the line leading to the carb etc.

Is there supposed to be suction in the line from carb to filter to when trying to start?

Not clear as to what "spray" and "manifold" mean but there is gas pooled inside the clear gas filter and gas in the portion of the black tube after the filter, the end that plugs into the carb or whatever. Since the start button and kill switch do not work even though the wires appear to be connected, I am hot-wiring the starter by using the positive wire from the battery since I am tired of using the kick-start. I'll figure that out as soon as I can get it started. Nonetheless, it still won't start after I disconnect the gas line at the carb point and drip gas directly into the carb.

Part II: I did the plug test under a tarp to check for spark. Yes, there is a spark so that means there is a problem with one of the other "legs?" If there is a spark, does that definitely verify that I have installed the new CDI, solenoid,magneto and ignition coil properly?

The names of these parts are unknown at this point. What would cause the small gear that pops out to turn the large gear to be stuck? The starter motor turns but the small gear does not emerge to connect with large gear for starting. It worked for a while... does the wearing down of the battery have an effect...the small gear only emerges when it's turned at a certain speed by the starter motor?

Is there supposed to be a significantly noticeable and bright spark? I already did the test and there was a small spark. Would the appropriate spark be easy to see on a sunny day? I may have to redo the test under a tarp or whatever to make sure since it's sunny here. If the spark is faint and the coil etc are new, what else would have an effect?

Turning the large gear wheel w/ belt attached etc. by hand, it is easy, then more difficult and then easy and then more difficult etc. It's inconsistent. Does that indicate there is no hole in the piston? Also, doesn't the fact that fuel is being vacuumed into e.g. the gas filter and line to carb a sign that pressure exists?
