Tuning a Generator?

[Diggin It]

Quick test run with Kill-A-Watt connected.

No load, 121.3 V with little variation. Frequency about 63Hz with slight variation to about 63.5 or so. Energize a 1500 radiant heater, you hear a slight change in engine tone and the frequency drops to around 61 Hz. De-energize the heater and the previous numbers come back. Heater has two switches to select lo or high. With only one switch on, the frequency is in between, around 62Hz.

I have no idea how to adjust that or if it's even possible. Or if it would matter.

That means its running a little fast at low load. Not enough to be trouble. It probably settles to 60HZ at about mid capacity and a little lower at full load. Not bad.
