hi,guys, I'm new to this site, looks really good! My problem is in trying to start up my heating furnace, equipped w/ an '86 Bentone FC4A burner(Suntec pump), after a year's idleness. Fuel atomizing but not igniting, or rather, igniting intermittantly, chuffing like a locomotive, and filling the room with partially burnt, atomized fuel. What am I forgetting to do?
