Re: need carb needle reset settings for 49cc 4 stroke hua-sheng bike engine kit? plz
Welcome to the forum!
The generic starting point for any fuel or air screw on any carb is 1 1/2 turns out from lightly seated. This will get the engine started so you can fine tune the adjustment after the engine is up to operating temperature. On rare occasions you might need to turn it 1/4 turn or so, either direction, to get it to run decently during warm up.

HuaSheng carb adjustment info
(from Quenton Guenther)
"Adjusting the EZM carburetor
________________________________________
In order to adjust the carburetor it is necessary to warm the motor up first. The motor should have at least 5 minutes running time before any adjustments are made.
On the left side of the carburetor near the front is the idle mixture screw.
On the EZM motor the idle mixture screw is a fuel adjustment, not an air adjustment.
Simply adjust the screw for maximum idle, and then turn the screw approx 1/16" counter-clockwise [slightly rich].
Check the throttle response, and adjust the mixture if there is a hesitation. Turn screw clockwise if it "bulks" and then catches on [rich], or adjust screw counter-clockwise if it accelerates and then drops off quickly [lean].
Have fun,
