View Full Version : Propane Conversion

A year or so ago, I bought a small generator. Its a McCulloch Mite-E-Lite with a 4hp B&S gas engine from around 1968.

Nothing really fancy or powerful. I bought it because it was very simple - it generates straight AC, but the only regulation for voltage (and, I assume, frequency) is via the engine governor.

Anyways, I bought it because its portable (one person can easily lift it with a little grunt) and I figured I could run some lights and simple appliances in the event of a power outage. Could also run simple hand tools at my wife's garden at her parents' property w/o a 300' extension cord.

I have it apart and it has almost no wear inside the engine. Figure I'll get a cheap Harbor Freight hand truck and mount it to that so I can cart it around.



What I'd really like to do, however, is convert it to run on a B-B-Q sized propane tank. I figure propane is a heckuva lot safer to store than gasoline, and if the power is out, the gas stations are down for the count.

I know I could just purchase a propane conversion kit, but they sure are expensive for this project (more than I paid for the whole generator).

Anyone know of any resources that would show how to build a propane converter using off-the-shelf parts?


I have another engine that I jury-rigged a simple propane injector using a plumber's torch and small propane bottle. Worked pretty well, although it had no regulation and I worried about the possibility of backfeeding into the bottle and blowing things up.

I have a drill press and small lathe as well as a milling attachment I built for the lathe, so I think I could probably build something if I knew how.


Anyone have any sources for something like this? (or warnings that this is a dumb idea?)


Thanks in advance,

Chris

Just throwing this out there too...

I live in the city and we have natural gas. I know the regulation could be dicey, but perhaps thats a better way to go than propane?

Or, if the conversion was similar, a dual fuel setup would be cool.

Actually, the ability to run on gasoline, propane, or NG would be the ultimate in flexibility...

Hey Chrisser, here are a few links that may help point you in the right DIY direction...

http://www.otherpower.com/otherpower_propane_convert.html

http://www.propane.tx.gov/research/mowercoursebook.pdf

http://theepicenter.com/tow102899.html

I ran accross this statement while finding those links:

Many federal, state, and industry incentives are available for farm use of propane and propane-fueled equipment. A local agricultural extension service or state department of agriculture is another source of information for available incentives.

Thanks Tufhelp,

seems to be enough info in those links to do what I want, at least with propane.
