gy6-150.
if I connect a vacuum gauge to the intake manifold to adjust things, what should I expect to get for a good reading.

You will not get a good reading due to it pulses to much due to only being one cylinder.
If your talking about tuning the carb for the correct mixture follow this procedure.
