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.
