I am going to be getting a tri-fuel generator for back up power. We have been without power for about a week, three times in the past 17 years. And several more times for a day or two. My current generator is an old Coleman contractor 4800w generator. It's noisy and the power is dirty. It's also oversized for our needs and I am tired of draining fuel out of it when idle. I am looking at a tri-fuel modification of either a Honda eu2000i or a Yamaha ef2400is. The propane option is because it stores for long times without degradation. We also have a large tank which may be necessary to use in the event of a serious earthquake. The two places that do these conversions are: www.generatorsales.com Central Maine Diesel 1594-D Outer Hammond St. Bangor, ME 04401 or http://www.propane-generators.com/ US Carburetion Kit Center 416 Main Street Summersville, West Virginia Does anyone have a propane generator? Has anyone dealt with either of these firms? If yes, any comments on them.
