Hi guys. Can you recommend me a good main jet size for a stock 50cc gy6? The carb is pz18j and the stock jet is number 79, but the scoot seems to be running a bit lean. I set the needle at the mid position. The spark plug is still white-ish. I run it mostly on 3/4 throttle. I live in Europe at sea level if it makes a differrnce. Thanks in advance and sorry for my bad english. Cheers.
