even tried with the air box off so see (since it seems starved........somehow) and it didnt help either.
after cleaning that carb, if it doesnt help, could it be the cdi?
I also plan to get my multimeter from work and test the coil........
Any clue how to test the cdi? i have very vague insrtructions from a gy6 service manual.......
unless im reading it worng..... but ive read it several times over.
This site has a pin out for the Gy6 cdi. If you can't get it, I could send an attachment for it. It sounds like carburator or as someone else said, a vacuum leak. As was said, the intake manifold nuts are a prime place to look as they have loosened up on me several times. Also, cracks in the rubber manifold. I wound up mounting a small block of wood under the carb to keep it from bouncing up and down. Also, could be the electric choke. Check for 12v first, then pull it out and let it cool all the way down(put a cold pack on it), put 12v on it and check for movement of the silver pin. Should be aprox 1/2 inch. Good luck.
