I treid cleaning the carb, and after taking it off and on 5 times I just bought a new one off Ebay for 28.80 shipped....problem solved. Sounds like your card is clogged

I'd verify that you have a good fuel flow to the carb- are the vacuum lines hooked up from the intake to the carb? Is the fuel enrichment valve (choke) working/wired correctly? Sometimes the carb isn't the only culprit!!! A valve adjustment is always good when getting a used GY6 - as most people don't do simple maintenance.

I just removed the valve cover and you can see both valves. I set both of mine at about .005. You have to make sure you either are at TDC or if you dont want to do it that way, make sure the valve you are adjusting is on the Cam lobe base.
