Honda generator extended run build

My brother has a propane powered generator in his 4104. It is a Kohler, but instead of 12 k diesel it is 7.5 propane. It has worked well for him. It even set for about 12 years and fired up with no issues. I believe that they have propane conversion kits for those small Hondas. It may be a different mfgr. that offers them though.

I've read from people who have done the propane conversion that the Honda generators don't live as long running on propane. Something about temperature

If everything is adjusted properly, there should be no issues, except for a little loss in power and output. Im sure sone just slap on a kit and never make sure everything is right. But your setup works, so stay with it.

I think usually the compression is raised a little for propane conversions, but not that much so one should run on it OK, but it's a 'dry' fuel so mixture control would be important, and running rich would not be as helpful in temperature control as it is with a gasoline engine since you are not gassifying the fuel in the cylinder. So the timing would be more critical for temperature control.

Yes, you loose the advantage of the propane's equivalent of higher octane. A 9 1/2 to 10 to one would benefit to that advantage, resulting on almost equal power/economy,but the cost to change pistons, etc would wipe out the benefit compared to engine set up with propane from the factory.
