Gy6 starts idles dies
I recently bought 2 gy6 scooters with problems and I am trying to make one work. I have the bms starting with the help of spray and then it idles for about five mins before spurting and dies. I've cleaned the carb and sprayed starting spray around the intake and hoses to check for vacuum leak. Also if I give more than half throttle while running it dies. I do t know what to do

Does it have a fuel pump? Is the fuel filter clean? What shape are the vacuum lines in? If you spray in the carb at the end of the five minutes does it keep running? This could either be a clog in the fuel system or an overheating electrical component.

A CDI is cheap and if the scooter dies with a spray you'll know it's not the carb. If it still quits then test the pump and see if it's spraying at that point. If it is, check for spark.

Sounds to me like it's running while auto enricher is on, then quits as engine warms and enricher closes. This would mean plugged idle jet or idle jet passages. This would also explain why it dies when you try to open throttle while it's running...You're giving it any extra shot of air, and it is still only receiving gas supplied by enricher. When you cleaned the carb, did you remove the jet and spray cleaner through to verify that the pathway to the tiny little holes located in front of the butterfly are open?
Before I spent any money on electrical components, I'd make sure fuel system was right. Fuel delivery lines, vac lines, and fuel filter, should be replaced...especially if they are OEM, black, rubber hoses. Ethanol laced gas turns these to mush from the inside out, over time... I would also pull the valve cover off, check clearances, and adjust them if needed. |
