Hi,
My crossfire 150r with a 150cc gy6 does not want to rev over 4500 rpm. I just changed the cdi, plug and coil and have not tested the rpm since the changes (only time to fix, no time to test ride), but I heard that the electric choke can stick closed killing performance.
Can someone point me to a topic or article on how to check to see if my electric choke is stuck closed ?
The carb has an airbox intake of appx 2", but I am not sure which model carb it is.
Many thanks, Chris

remove the choke from the carb, measure the needle from the top or bottom of the housing. hook 12 volts to it, let it set for 10-15 minutes. remeasure, it should be longer
