I've got a 10 HP Kohler generator, and I'd like to install one of the
Natural gas conversion kits on it so that I can run it for long periods of
time if needed. I was wondering if anyone had any experience/advice on doing
this?
We just had a tornado in our town and our power was out for 4 days. The
generator worked fine, but it was a pain in the a** having to put gas in it
every 5 or 6 hours, and having to wait in line at the gas station with all
the other guys wanting to fill their gas cans.
The makers of the kits claim no drop in performance, but when you buy a
"dual fuel" generator they list a lower wattage output when running on
Natural gas than on gasoline.
Thanks in advance for any replies!

Yeah - people claim many things.

I believe that the physics has something to do with NG displacing more
of the air in the fuel-air charge.

We have AARVARK kits on a couple of 8000 watt units.
The kits have been ok on propane and gasoline.
I've not had a chance to run them on NG.

Part of the answer depends on how close the engine is to max power on
gasoline.
In one of the other threads, someone mentioned that their engine had
sufficient excess capacity not to derate for NG.

Be aware that your NG supply can be interrupted by the supplier.  New
Orleans had
a significant disruption due to many (read most) of the meters being ripped
out.  Initially
it was low pressure.  later it was that the supplier cut the flow due to
danger of fire/explosion.

Some of our remotes tower sites have standby gen sets that can from, the get
go, run on gas, NG or LPG for weeks.

If you just want emergency power and can stand the noise, then the tri-
fuel conversions with on site-propane to back up the NG seem best - if
you can deal with or ignore the noise.

 Per philkryder:

Is that to say that a given engine runs louder on NG or Propane
than on gasoline?
