I have been trying to find my trouble with my 1977 Kingsley motorhome running badly. Took apart the carb trying to find out if needle and seat were dirty, installed new spark plugs, new plug wires, with no good results. Finally ran a compression test on the # 3 cylinder because that old plug was black and the results were absolutly no compression at cranking speed. Took off valve cover and discovered the valve springs are not broken and are working. The next step is to take off cylinder head. Must be a hole in a piston or a badly burned exhaust valve. Next I applied air pressure to the #3 spark plug hole and I could hear the leak in the exhaust pipe. I am not looking forward to tearing down the engine to get the head off. I'm TOO OLD for that. I will begin a search for a shop in the Fort Worth, Texas area. DOES ANYONE HAVE SUGGESTION ABOUT WHO?
