Hello, I have a Little Giant Propane unit with my Truck mount machine. This year as I was Testing the unit after the winter I noticed that the burner was not lighting.. Pilot light is strong and I disconnected everything attempting to reset the regulator but it didn't help. The only thing that has changed since last time I used it is the cold water line going in to the unit, which I recently changed since the last one split. The new hose is a size smaller because that is all the shop had at the time. Any suggestions would be appreciated.
