Hi all
thanks for all the reply

Its a gas genset. I have no clue how long it sat and if the old owner
used some stabilizer in the fuel.

I am guessing that it sat for at least 2 years.

And it surges all time time. load. or no load. you can even see it
surging on the boats volt meter.


I have seen this problem many times on generators that rarely get used.
Typically, the homeowner doesn't run the generator until there is a
power outage, at that point it won't start and they bring it in to be
fixed. The first step is to drop the carb bowl and clean it, especially
the jets and needle and seat. After a couple visits they start looking
for a propane-powered unit.

Sometimes you get lucky, try turning the high and low speed jets out a
turn, then turn them back in. Sometimes this will clear an obstruction
in the jet.

What is the make of the engine? The generator is made by Generac I
think, but is the engine a Briggs& Stratton or a Tecumseh?
