Ok everyone, I opened the carb AGAIN to find the needle had come out, well I replaced and secured it and my scooter runs now!!! but guess what, read the first part of my story
"The scooter ran fine, I was test riding it up and down my road. It then slowed down. It ran from then on but if I went over 25% throttle, it bogged and would stall."
THE SAME THING THAT I STARTED OUT WITH IS HAPPENING NOW! I'm going to throw this thing in my trash can and let the dump truck come get it >.>

This is REALLY frustrating me, The scooter will start and run at VERY LOW RPM with WOT with little to no gas in the carb and the fuel in disconnected. When it has just a little bit of fuel left it it actually revs up with me holding WOT with a LOT of power. The scooter jumps forward and then runs out of the remaining gas. Again, this ONLY happens when fuel is disconnected and most of the carb has been drained like only fumes are there. I removed the carb and tested the float. It works perfectly. When the float is fully lifted no fuel comes through the fuel in port. I removed the carb and the bowl from the bottom of it and tested it and it works perfectly. I am at a loss.

Thanks for the tip alley, I will try that. I have managed to get it to start.
Just to clarify, the card does not overflow anymore, at least not to the overflow valve.
The ONLY time I can get it started at this point is if I remove the fuel line from the carb (Which is purely gravity fed at this point) and if I drain the carb. Then it fire up BEAUTIFULLY but only for a split second with a large puff of smoke and stall. (Obviously, since there is not anymore fuel to burn.) if there is ANY fuel down in the carb it refuses to start... Any other tips? I am going to go take the spark plug out and try and blow some gas out. Alley, if my scooter ran for that split second then stalled with no fuel supply in the system, wouldn't that mean I burnt any fuel in the cylinder? If so, why would the scooter not run if there is a fuel supply? The gravity fed fuel supply definitely is bringing down fuel, and the fuel is not overflowing the carb.

Just realized that I have fuel in my vacuum lines. My petcock is inline right before the fuel in, I am going to try and bypass it now and see what happens. Any other advice is still welcomed.

First off, I don't have access to these boards from tapatalk, anyone know why? Secondly, my GY6 is the 1P57QMU
What I've done.
The scooter ran fine, I was test riding it up and down my road. It then slowed down. It ran from then on but if I went over 25% throttle, it bogged and would stall.
I cleaned the carb after that, and it didn't bog anymore but it wouldn't go above 25mph.
The piston in the carb was getting stuck, so I cleaned again emphasizing on the piston and piston walls.
IT STARTS! I can feel the power has returned, so I take it down the road. SMOOTHLY cruising up to speed when it stalls at 35mph. =[
I get it home and find out the carb is flooding (It was draing from overflow, emptied the float bowl and tried startingg again until the carb overflowed again)
I took the carb apart yet AGAIN! and cleaned the bowl out a little better and tested the float system with carb cleaner, it works fine.
I put it back together and tried starting again, the carb no longer over flows but it won't start... wierd.
After I while I took off the fuel in line and plugged it, i cranked for a while and it eventually cranked on STRONG for a few seconds then stalled (obviously)
My theory was the cylinder was flooding. I believe I am correct because once I get to this point listed above, the motor will try to crank and I can hear it igniting and sometimes it will run with WOT at a VERY LOW RPM, and then eventually stalls and I have to repeat the above until I believe the cylinder is empty.
Any advice on this? I am very frustrated at this point. I have tried to let the bike dry and a similar thing happens until it, what I believe, floods.

Have you adjusted your valves? It sounds like it could POTENTIALLY be closed valves, which is quite a problem sometimes. Another idea is to open up the CVT cover to see what's up. Check on the condition of the belt, rev it up without the cover on (on the center stand) and see if the belt is catching up anywhere. You might need a new belt! I didn't mess with my valves in any way. I had the CVT open and it seems to spin fine. Cant tell if its a clutch issue not applying the power, or a motor issue, and it isn't generating the power it is supposed to. Sent from my LG-LS980 using Tapatalk

Ok, so I traded my little 50cc for a 150cc, and when i got it home it ran fine and hit 45-50 for about 30 minutes. All of a sudden the the scooter struggles to get over 25. It started where when you pull WOT it would actually stall it. Cleaning the carb resolved this issue now it just seems to have no power. When i get to 25 i can hear a grinding/vibration come from the CVT case which wasn't there until after the carb cleaning and the scooter could hit 25 again. There is also a hose on my valve cover which I believe goes to the cvt case. That hose appears to be BLOWING, which is abnormal to me. Leads me to believe that maybe there is a valve issue? It does still blow out of the exhaust l, too. Please ask any question. I'd prefer not to buy a whole new motor.

Also, can anyone recommend anything that should be checked on these type of scooters? I noticed some times when I've been WOT on it and I come to a stop, it stalls. I'm thinking it has something to do with the open end vacuum lines.

I just traded my 50cc Peace Sports gy6 scoot for a 100 or 150 cc engine, not sure which. I think it is a 150cc gy6. Any way to tell? Also, I have a vacuum line coming off my valve cover and another coming off my carb, would any of you be able to tell me where they supposed to go? The scooter runs, I just want it to run right. I will post pics in a few minutes. Also if you could help me find the proper make and model of this scooter that'd be great as I am having a hard time finding parts, etc.

The plastics on this used scooter were garbage, as I'm stripping the plastics I'm falling in love with the frame, I want to try and mount the seat with no plastics. Anyone got pics of a similar mod so I can get some better ideas? Will post pics when fully stripped and when I start modding. Edit: as title says. I'll post the pics tonight. I want to steam punk it but I want to keep it as a skeleton style frame. I love the look Note 3

Thanks for the info! Started yanking the plastics off today! I had a wierd gunk in a compartment of my airbox. The compartment had a hose going to the top of the engine and another routed to my air intake I assume to create vacuum. The compartment with the gunk is otherwise completely seperate from the airbox, just the same piece of plastic. An awful smell it had, too.

Hopefully not the cam timing chain, I hate the idea of stock variator weights, too. I get the feeling that if you change anything on a chinese scoot, it is those.
