Hi all
I have a quick silver 7.5 KW genset
and its been sitting for a wild. we started it up and it wont hole RPM
it just surges
vroom-vroom-vroom

IT will generate power
any idea how I fix this?

A common reason for the surging is the engine is starving for fuel,
usually because the carb is dirty. Does the carb have an adjustable high
or low speed jet? If so, turn the jet CCW a bit to see if the problem
gets better.You may end up dropping the carb bowl to see if there is
dirt or varnish built up in the carb.
How long has it been since the engine ran? Was the fuel drained from the
carb or was a fuel stabilizer used?

==================================

You don't say whether or not it is gas or diesel, or whether or not
the surging occurs with no load or not. If gas, the most likely
reason is a gummed up carburetor from sitting idle (you don't say how
long). Is the choke opening up properly after it warms up? If not
you could try spraying some "Gum Out" into the carb. When the engine
is surging, it is generating something other than 60 cyce power which
can damage non-resistive loads or electronic gear. Test with light
bulbs or electric heaters which don't care about line frequency.

Adjust the low speed air jet on the carburetor and you can smooth it out. I
have to do mine every time it sits for a long time.

Start with fresh gas, clean the carb... at least that's where I would start.

More than likely your carb is gunked up from sitting. Clean it. On one I
had to disassemble and run a wire through the main jet.

After you get it fixed then next time you expect it to sit for a while turn
off the fuel and let it run without a load until it burns up all the gas in
the carb.

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.

Bilge- What have you done to the fuel system? Is your boat also gas
powered...and if so, do the mains also have these problems?

Is your engine breathing freely? Are your filters clean and your air intake
scuttles open?

Is your genny fuel injected or carburetted? At the very,very minimum, you
should be changing the genny's fuel filter(s).

You might also have condensation water in your fuel tanks...wanna know what
it's like to activate a steamship from the James River "Dead Fleet"? Ya lurn
about that trick fast when your boiler burners start sputtering.

Your voltmeter surging means that the genny is self-excited. You cannot, at
this point, rule out a governor problem, but this is sounding more like a fuel
/air problem.

====================================

I'd say that it is either the carburetor or governor, probably the
carb given the history of sitting idle.

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?
