My port engine (200 hr.
My port engine (200 hr.)is experiencing a torque loss plus black wet plugs. Fuel pump pressures and plugs are identical with the starbord engine. The only difference is that the port timing has been "adjusted" by two different mechanics. Am I correct in thinking you have to physically disconnect the electronic advance prior to setting the crank timing with a timing light? Then reconnect the ECM and set the advance with the diagnostic tool? Retarded timing would explain both the power loss and the rich mixture due to incomplete combustion.
