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.

If you have a standby genny for your house, you should run it for at
least an hour a week, and under load. First, you want to make sure it is
running properly, in case you need it. Second, you want to cycle through
the fuel. Third, you want to make sure your electrical hookups are wired
properly. Fourth, you want to become and remain competent in use of the
device.

In fact, even on your boat, you should run your genny at least once a
week, and for the same reasons.

We have a 500-gallon liquified gas tank buried in our yard to fuel our
hot water heater, gas range, fireplace, and as the primary fuel for our
main heat pump. It was a minor expense to have the plumber run a line to
the household backup genny.



You did not address his question Harry. You only posted to brag about your
"household backup genny". So typical of you.

g...looks like others have addressed your question and there is nothing more
I can add.

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.

bg clarifies:

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.
