The oil and fuel have been mixed in the proper ratio

The carburetor on your Cobra motorcycle is quite adjustable. Figure 49 shows its range
of adjustment and in particular what adjustable component affects what range of
operation (specifically throttle position).

FUEL SCREW ADJUSTMENT: Adjust for maximum idle speed
The fuel adjustment screw is located on the left side of the carburetor. It is the smaller of
the two adjustment screws and requires the use of a small flat blade screw driver for
adjustment. After adjusting for maximum idle speed, use the idle screw to adjust the
desired idle speed.
