I got a panic call from my wife "batteries at 15%, genarator not working! Call home!"
Luckily I was on my way home.
Turned out the studs and the propane carb adapter had vibrated loose and the carb fell off!
The engine is a old Honda G400/ 3500 watt generator with a double pulley driving a another alternator for battery charging.
As well the rod between the governor and the carb had worn and broke apart.
It was easy enough to bolt the carb back on.
To repair the linkage a nut from those cheap nut/bolt kits was soldered onto the worn , ovaled out linkages and a welding rod was used for the new rod.
Unit has worked great since.
Lesson learned ...be vigilant about preventitive maintenance!
