G, day everyone
I am new to motorised bicyling i've had my 70cc Zbox for about 5 months. I upgraded the stock carb to an 18mm miikuni. I dont know what is wrong with it. It revs really low and wont go over 20km. I have changed the main jet bigger and smaller changed the float level. Nothing seems to help. It starts working properly after you turn the fuel tap off and it starts to lean out. Just before it runs out of fuel in the bowl it screams and picks up speed incredibly.
Any help would be great thanks
