Mike, I don't disagree with your cleaning procedure, however, I don't believe that an owner should take on such a labor intensive and critical procedure to perform a non-critical condition Removing the mixture control unit requires the removal of the fuel distributor. Unless you have experience with this procedure the fuel distributor could be easily damaged. Replacement cost for this part is now in excess of $700, less labor. As long as the sensor plate and adjoining venturi are clean, deposits (grime) coating the inside walls of the mixture control unit should not effect the performance of the fuel/air system. Spraying the control unit with carb cleaner while the engine is running will cause the grime to liquefy and be sucked into the combustion chamber where they will be safely burned out of the system.
