I left my scooter parked at a business (indoors) for 45 days and it no longer runs after I picked it up. It ran the best ever when I parked it and I know that nobody rode it either. I had just installed a new belt, variator and rollers plus I have a new air box which I haven't installed yet. It seems like there is a gas line issue. I thought it wasn't getting enough gas but now it seems its getting too much gas? There are 2 hoses that are unhooked and 2 nipples that have no hoses hooked to them. The scooter runs without the hoses hooked up but won't run if they are hooked up. The nipple on the exhaust pipe (left) side spews gas when you get it running. The loose hose on the right side runs to the gas tank beside the hose that has the fuel filter on it. The loose hose on the left side connects to what looks like the top of the engine. There is a 3rd hose that connects to the top of the rear end of the cvt housing and it broke awhile ago and its possible that it connected to the left side hose that I'm unsure where it goes other than the end that's still connected which runs to the top of what looks like the top of the engine. I've looked at other diagrams/pics and they don't look like mine. Another thing I noticed is that if I take a hose off a nipple that I know has been used the nipple is gold/copper colored but these 2 nipples that aren't connected are silver. I'm not sure if that means anything or not. Just \tying to be complete with the details. Any help would be appreciated. I don't see any way to post pics but I'll figure it out quickly.
Hope this link to youtube works as its my scooter showing the issue

Sorry about the way I had to post. I'm using a phone as my only option. Would replacing the carburetor fix everything? Or does it seem like a bad carb issue. I just downloaded the owners manual from herè, maybe it has diagram

 That port vents the fuel bowl and should be open to atmosphere. Float needle may not be seating properly. One technique to try . . . |

Unfortunately it didn't work. I believe the carburetor is bad. Its like the choke is stuck on. Gas leaks out of that little valve, the exhaust manifold and actually at the bottom of the carb. Im assuming the float needle is the thing u can move up and down with your fingers thru the exhaust manifold. I took the top off the carb and a spring, needle looking thing with a plastic thing (float) & a rubber seal on top. It was all clean as a whistle. And the float moves fine. It absolutely gushes gas out of every place gas could possibly come out. It looks like there might be a seal under the carb that is leaking too. I'm guessing I'll just buy a new carb, lines and try to figure it out or take it to a repairman. Its weird, when on the stand and I get it running if u run it fast it doesn't leak but as soon as I let off the throttle it leaks like crazy. Its just aggravating bc I have bad back problems and can only work on it for short amounts of time.

I'm just going to buy a new carburetor and while I'm at it I need a new intake manifold. As stated earlier my scoot is a 2014 Cy150 Paladin 150cc. Im trying to find out what exact carburetor to buy. I'm buying off amazon or a website, no ebay. I have a new air box that I didn't put on yet and it says it's 43mm. I bought it thinking it was compatible but now when I go to different sites one says the carb's size needs to be 37mm where you put the air box to the rear of the carb and ano th her says 43mm. Everything is pretty much the same regarding the intake manifold being 24mm. I've looked at the manuals and it doesn't have the sizes. In an above comment there's a link to a deni(deni?) carb but it doesn't have measurements. That carb is expensive compared to amazon that sells them for around $25-50. I don't have calipers to measure myself but could buy some if they aren't too expensive.
Any idea what exact measurement I need to use 37mm or 43mm for the carb? I've looked everywhere with not much luck. Sorry to be a nuisance

Hello, Shane0613, I currently have a 2012 Taotao EVO 150cc, but before that I had a 2010 Jonway F One 150cc and I had a similar problem with fuel leaking all over the place as soon as I stopped the engine. it turns out my problem was a piece of junk got by my fuel filter (from gas that I bought from an old gas station with probably 50 year old tanks) and went to the bottom of my float bowl and stopped the needle jet from seating all the way down so fuel kept flowing threw it. I ended up taking the carburetor apart and cleaning it, all was good afterwards.
But I believe you have a different problem, the nipple that you don't know what its for, it's for the Vacuum hose that comes from your intake manifold, it's actually called a "cut valve"...it's there so when you let off of the throttle or turn the scoot off, it doesn't backfire.
So, you know that extra hose you said you had and were trying to get it attached, it needs to be attached right there. You see the vacuum hose starts at the intake manifold and comes up to a tee, where one hose goes to the vacuum pump (located about halfway back to the fuel tank on the left side/kick starter side) of the scoot, while the other hose goes to the right side of the carburetor, right behind your idle screw and usually this hose will have some way of attaching to the topside of the carburetor so that it kinda wraps around it.
I can send you pictures if you need me too, but there are a couple of good shots of it online. Just type in GY6 carburetor, and you can even watch a couple of video's of guys disassembling them.
BTW you want/need a 37mm carb if your gonna replace it.
