Please help !

Any chance you are just overfilling the gas tank and wetting the venting canister element. Have you tried running with the gas cap loose?
What is a spark plug read indicating? Have you observed if the carb slide is rising properly, and checked for a fuel vacuum-petcock issue? Have you referenced the service manual and Ohms tested the trigger/pickup coil and ignition coil . . or tried a replacement DC-CDI (http://www.gy6store.com/GY6-Performance-CDI-DC-stock-replacement-GY6-Performance-CDI-DC-stock.htm?categoryId=-1) . . or the ice test (http://scootdawg.proboards.com/post/257574/thread) ?

I've observed the slide in the carb and when I go about halfway with throttle it rises but if I go further engine bogs and slide starts to drop .... As far as the vacuum valve on gas line I disconnected fuel line after filter and when engine runs gas pours freely I've also set up a gravity fed system and still no change , never put spark plug on reader but plug is burning tannish ... Everything else you've said is gibberish to me sorry I was given this scooter for free it wouldn't start , changed battery , fuel filter , took apart carb and cleaned and regapped plug and I got it to run just bogs now over 30-35 .... I'm new to the small engine world forgive me for not knowing what some of these parts are but if u can pass me on a list of what u think I greatly appreciate it and thank you for taking the time to reply my friend

Where's the school-CDI located and what's the ice test ???

Your description of diaphragm functioning does not sound right. It should stay up at full throttle and high rpm. Maybe it's torn, or not seated properly.
-
The only thing that makes me think that it's not the diaphragm is that as I rev engine up it slides up and stays up and it's not until I go further with acceleration and engine bogs then the slide starts to drop and if I hold the slide up engine still bogs

Yeah, that makes sense.
I had a similar thing of a 50 cc scooter once. I tried everything and couldn't get it to work. I finally gave up. A buddy took up the challenge. He replaced the carb (which was working fine as far as we could tell) and "VROOM!" it was fixed.
