Been thinking of buying a second RV genny with electric start, so when it's cold I won't have to pull start it. Which kills my arm. I found this genny that is a dual fuel gas/lp.

However, I remember as a kid, we had a chrysler flat had that powered our irrigation pump. It was a bear to start in the summer on LP.

I know an old man who had an F250 with a dual fuel carb. If I remember correctly he said he would start it on gas and then switch over to LP in the winter. His carb had a water hose going to it to help warm up the LP.

Many years ago, I remember seeing some farmers with LP tractors. What kinda of issues did they have?

So, my question is will a dual fuel genny start in the winter on LP? Their selling point is LP doesn't go bad like gasoline. Forget the fact that this genny is most likely not made in the USA. Like everything today, TV's, computers, Washer/dryers, refrig, if it breaks it's a throw away.

Gas/LP genny
 
If the temperature is above zero and it doesn't start as good as gasoline it's not the LP's fault, there is something wrong with the system.
 

Unlike gasoline, propane is a gasous fuel. For example, it's vapor pressure at 0 degrees is 40 psia which should provide for easy starting. Propane vapor does increase the voltage required to jump the spark plug gap, as compared to gasoline vapor. Therefore, the ignition system should be maintained. Sometimes the plug gap may be reduced for propane fuel engines.

IMO - propane is a good cold weather fuel, since it is a vapor there is no choke required.
