I assume the engine speed is changing when you adjust the screw??
The actual rpm's should be 1800. If the generator output is noisy (not a clean signal) it can confuse the meter. You can put a load on it using heaters, they are not so sensitive to frequency (the old ones with no electronics). A load might calm down any noise interfering with the meter.
