When I purchased the boat this May, the previous owner had to replace the carb. When we surveyed the generator ran great and the voltage was checked but the surveyor did not have his frequency meter and suggested I verify the speed was correct.
Fast forward - I really did not use the generator this summer other than run it with a load at the dock on occasion. I recently ran it with the air conditioning on to put a bigger load on it and noticed a sound which I can only describe as a slight squeal from the a/c unit. I wondered if the frequency was in fact off since there is no noise on shore power.
I borrowed a meter with HZ reading on it last night and saw it was at 58hz. I left the manual at home so I just raised the idle screw to see if it would raise. It did but fluctuates more that I expected.
What is correct method of checking and adjusting the frequency? The manual has me scratching my head. Should I have set it with no load? I noticed when I turned on the stock inverter the hz dropped to 56. Is there more than just the idle setting?
Thanks in advance,
Mark
