Anybody that owns a generator should have one of these:
Heck if you use AC line voltage for anything, you should have one of these:
It will read voltage, frequency, and current.
Your generator will have an easily accessible governor adjustment, get your load energized and running, then final adjust frequency to 60 hz.
You can also just wing it by setting your generator speed to 61-63 hz un-loaded expecting that the operating load will slow it down to ~60
Don't worry about the voltage, it's fixed and calculated such that when there's no load, it's going to read a little high, it will drop as you add load, and unless the generator has electronic voltage regulation there's nothing you can do about that fluctuation. It's the nature of small portable generators.
I have a 15KW ST head that i turn with a 32HP slow speed stationary diesel engine, i use kill a watt to set my speed. The ST is an 1800RPM(precisely) head and they say if you over-speed it above 1950, the windings will come apart on the armature................. explosively.
