Well I had the well plugs resealed on the carb and also had the electric choke installed and I am still experience an engine that sounds great when running but eventually stalls out. I put a new temperature gauge in that doesn't use the electric feed and my tester said it had 12 volts going thru it. So I hooked up the choke to that and it doesn't open a full 90 degrees. So my question is does anyone know what the 74 455 engine temperature gauge line voltage is? And does it take a full 12 volts for the choke to fully open. Say it has 9 volts going thru it will it only open up 75%??? Otherwsise, I have the same symptoms, coach starts, runs fine and eventually stalls. I can restart the engine after stalling (3-5 minutes) and it will run for a bit. I am beginning to wonder if I have a leaky exhaust valve that causes back pressure in the manifold or some type of restricted exhaust (have replaced two mufflers as well). I am getting nowhere quick. I wish I had more tools to check stuff. If there is anyone near Lowell MI or Grand Rapids MI that could assist in the problems I would gladly pay for the help.
