Two requirements for running satisfactorily on kerosene are missing on your
engine. Compression ratio must be much lower; I do not recall exactly what
ratios are used but I think about 4 or 5 to 1. A lot of intake manifold heat
or a separate "vaporizer" to get the kerosene vapor hot enough to ignite
readily. My wife mistakenly put kerosene in the tank of a hot lawnmower. The
engine started but knocked severely with lots of white smoke from the
exhaust.

Many years ago, I was told that a small (or large?) gasoline engine will
run
fine on kerosene. However, it will only run after it's warmed up, needs
gasoline to get it started and running.

The application for this is remote pump houses, and fire pumps in remote
locations. The engine has a valve system for the fuels. A couple galons of
gasoline are kept on hand, and replaced every couple months. A larger tank
of kerosene is also present.

The operation plan is that if the pump is needed, the operator comes in.
Sets the valve to "gasoline" and pours in a galon into the smaller gas
tank.
Runs the engine to get it started, and warm, and then changes the valve to
kerosene. When shutting down, it is then necessary to either run the
engine
dry, or change it back to gasoline.

Now, to make this personal. I have a Coleman generator at home, with a 5
HP
Briggs and Stratton engine. Supposing for the sake of discussion, we have
an
extended duration power cut. Has anyone personally had experience with
this?
Is this a correct description?

I've got maybe 5 galons of gasoline at home, and about 20 galons of
kerosene. It would be very nice to use a quart of gas to get my generator
warmed up, and then pour kerosene into the tank. But I'd sure feel more
reassured if someone else out there had done this, and knows that it it
will
work.

Would have to run the generator dry, when shutting down. So as to allow to
restart the next time on a quart or so of gasoline.

I appreciate any ideas, advice, or thoughts.
