I have a bit of knowledge about working on cars but I have never worked on a scooter before.  I found some one selling a Chinese 50cc ruckus clone "for parts"  I went and talked to her and she said stopped using it about 6 months ago and it was not working.  so  I thought this would be a fun project and a way to learn about scooters.... I was thinking it would be super easy to get working.... probably replace a few things and do an fluids change and be good to go.

I check the oil level and it has oil.  I will replace it as soon as I get it running but want to focus on getting the scotter running then will replace all the fluids.  I did not want to put in new oil and then have to drain it if later I had to take apart the motor.

SO I take off the cover and all the fuel lines were falling apart..... No biggie replaced all the fuel lines... Then there still was not fuel getting to the cab so I replaced the fuel pump.  also I look in the fuel tank and see rust.  so I empty the tank and rehad it.  I got a new fuel sensor and install it.... I got all the rust and gunk out and its good as new...   So fuel flows to the cab now... I now have a clean tank new fuel lines. new fuel filter and new fuel pump.

but it doesn't start.   The stater cranks it just doesn't start.  SO I do a bit of research online and from what I found you need fuel spark and compression.. seems simple enough... from what I have read if you have a scooter that doesn't start it most likely the CDI or a carburetor issue or spark plug issue.  SO I replace the Carburetor the spark plug and the wire, The starter Cap. I take the plug out ground it and look for spark.  I see spark so woo hooo making progress....

I crank it up and still doesn't start.   Now I am getting worried and i'm not sure what to try next.  so I go get some started fluid.  and I am able to crank and start it Wooo Hoooo.... I'm getting excited my scooter is alive... and then it dies.... wow that was short lived excitement.   so I hit it with some more starter fluid and try to adjust the idle so I can keep it running...    no luck... it keeps dieing after a few secs after starting with starter fluid.  so I start it and try and gas it to see if I can just get the motor warmed up and see if it will keep running then... well it bogs down and just dies when I gas it.  So I try adjusting the carb air/fuel mixture screw and no affect.......

arrrrrrr soooo  I am guessing a I have a vacuum issue??  This is a guess??  I check all the vacuum lines and I do not see any cracks or holes.... or anything off.... I have not replaced these lines yet.... 

so I am wondering if anyone can help me out and try and help me find what is wrong with my scooter... I would love to be able to figure this out and not have to give up and take it to a shop.   If some one has an idea whats going on or what I can do next any help would be greatly appreciated... Thank you in advance
