Hello everybody. I've ran out of ideas on what to do next. my 150cc gy6 version wont start unless I inject gas behind the spark plug. it roars to life and shuts down bout 3-5 seconds afterwards. So that tells me I'm getting spark. I do have fuel coming out the drain bowl hose so I'm assuming that there is fuel getting to the carb. I thoroughly cleaned out the carb and made sure all holes in jets are cleared, so I'm at a loss on how to proceed. Please help.

The Motor is telling you once it uses the Fuel you introduced the Carb is Not supplying Fuel to the Motor.
Do you have a fuel pump?
Have you checked the gas cap vent?

Hello.
No fuel pump. it is gravity fed. and I bypassed the fuel petcock, and drilled a tiny hole on the top of my gas cap.

Ok so you should have fuel pouring outa the fuel line directly at the carb correct?
So then if you open up the carb fuel bowl drain screw fuel continues to pour out correct?
Have you tried hand choking it? block the carb off with your hand and hit the starter? You can even keep it running that way if she fires by manipulating how much your hand covers the carb. she should suck fuel if there is any by hand choking it...
Good luck..

Check intake gasket, and carb for vacuum leaks.

Thanks for the advice guys. I was able to get it up an running again. Turned out to be a CDI problem. Seems like its always something simple that is overlooked  |
