However, tank valves were packed with junk. I am guessing fuel pump could not supply required delivery to the engine. Currently replacing all fuel hoses, fuel filter, grommets and cleaned angle valves/tank. We'll assess when reassembled after parts arrive.

Both of these tractors are at the age when the fuel system should be gone through from front to back. Pull the fender pan and tank. Clean the tank and shut off valves (2185 doesn't have shut offs) replace ALL of the fuel line and filter and clean the carb.
