what the F___?! IM LOST! >:(  By  ninjafatballz (Read 1,703 times)

yea I checked that like 5 times ... there is no crack...

yep.. checked all that.. no holes or cracks in anything whatsoever... and I tested the Petcock, it is working perfectly... I really am at a loss here..

Have you checked for a plugged exhaust or muffler.

I changed out the Cdi and the coil and wire.. didnt do anything with stator. nope, I have not checked for a plugged exhaust, but I feel it flowing out just fine, I dont think thats the problem. The float looked fine when I took the carb apart... I am thinking about getting a new carb, but I am seriously broke and I don tthink I have enough money to buy one . I am so pissed off that I just spent all the money that I saved up to buy a damn scooter that doesnt work worth a . this is supposed to be my only transportation.

I realize this is going to sound ridiculous but..... did you check the fuel filter or replace it? I had almost the exact thing happen to me when I bought mine. Ran perfectly during the test drive. Started it and turned it off probably 8 or 10 times while at the PO's house. Paid the man, hopped on and drove off into the sunset - for 2 miles. Sitting at a stop light it bogged down and when the light turned green, I tried to give it gas and it just died. Pushed it to the side of the road. Would start right up and immediately die.

Turned out to be a combination of 2 things:
1. Fuel in the tank was old and had de-stabilized. The little bit that sat in the fuel filter had gotten gummy thanks to the ethanol.
2. Fuel Filter was partially gummed up only allowing a little bit to flow freely. As the demand increased, the engine would bog down, starving for fuel.

Worth a shot anyway....

Either way, good luck!!

The first year I had my Xingyue, it acted similarly. One of the problems DID turn out to be the carb. Apparently, the Chinese fuel lines deteriorated from the USA gas, and messed up the carb so I couldn't get it cleaned and running right. I replaced it with a Mikuni carb off eBay for around $40. That got it running right, but during that first year, I still had to do the typical China-scoot mods.

Even though your petcock seems OK, I'd still replace it with a manual on-off one. The vacuum petcocks seem to cause endless irritations at speed.

My scoot also had MAJOR problems with the stock air-filters. Before modding anything, I'd quickly pull the entire air-filter assembly off the carb mouth, and see if by chance it runs much better. If it DOES, a simple UNI-sock filter might cure most of your problem. It's a long shot, but takes only minutes to try, and it might make a big difference. Just don't ride it with no air-filter for long.

Wish I could be more help, but what you're experiencing can be caused by many different things. Do try removing the entire air-filter setup from the carb though. I found my particular scoot would NOT run right with the stock "tuba" air intake. These engines can be a booger to get just right.
