Ran great but I screwed the screws to make it run better now won’t start does anyone know how many turns I need to re adjust a single barrel carb for a 70cc dirt bike roketa..2006
@ralphie ,Ralph, General settings for small dirt bikes. Turn the mixture screw clockwise until fully closed,then turn the mixture screw 1 1/2 to 2 full turns out. Adjust the idling screw until the engine idles nicely, turn the mixture screw slightly clockwise and counterclockwise until the highest engine rpm/rev’s is obtained. Re-adjust the idling screw again until the engine idles good approx 1500 rpm. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.
