Yes I did get the model. You can also skip any kind of spark test because that would not fit your symptoms. If the engine is simply getting up to a certain RPM (in your case 3800) and stalling, what is happening is the fuel is not making it from the fuel tank to the carbs. Where you would to start is by hooking a fuel line up directly to the fuel pumps, and sticking the other end of that fuel line into a portable fuel tank. When the engine runs everything on the inlet side of the fuel pumps is under a vacuum. When there is any kind of leak, what happens is air will leak into the fuel stream, and you would not notice that leak as any kind of external fuel drip. In most cases what the issue is, is a leaking fuel line, a leaking fitting, a leaking fuel filter, ect. And those leaks are allowing air to enter the fuel stream. Since it's easier to suck air instead of sucking fuel up, What happens is the fuel pumps suck air in through those leaks instead of sucking fuel up from the tank, and the engine ultimately starves for fuel and stalls out from lack of fuel. Does that all make sense. I do want to make sure you are happy with my service before you go. If you had a further question on the issue by all means feel free to ask.
