My generator is a Generac 5000 watt continues, with a Briggs 10 HP engine , It sets 10 months forgotten then the Indiana winter comes and it starts, high winds, down lines , 0 visibility and three day outages. I have removed the carb and cleaned it every year by the light of a crank up flashlight . Find the hose and siphon gas out of the mowers and tractors to run it on. I know all of that is the price I pay for poor maintenance and crapy gasoline. I saw a on demand propane regulator for a floor scrubber on Ebay that was new and cheap $23 so I bought it and put it on the Generac , that was the end of it. I was so pleased I bought 10 more regulators knowing all my friends would follow. I ended up putting one on my Toro with a 4 cylinder engine and my Case Davis loader with a 4 cylinder Wisconsin in it.Then I had to make a Propane Hand Pump to fill my 20 pound grill tanks from my 1000 gallon tank in the yard.To go to exchange tanks here it is about $18 per tank and they only put 15 pounds of propane in them ,around $6 a gallon.I paid 72 cents a gallon in the big tank. For the chainsaw I have to drive 40 miles to find E0 gasoline so it dont wreck the diaphragms and hoses. It seems like my stuff runs better on propane then gasoline,I am sure it is because all my carburetors are wore out and sucking air around the throttle shafts, so the on demand propane regulator covers it up with the automatic adjusting
