4.3L/LH 2-BBL (2004) was running hot (up to 190 deg) with hot riser on one side so changed the impeller and motor is now running 160-175 but now experiencing some dieseling unless I let motor idle for several minutes before turning off.
Used some seafoam during this same run because had trouble getting to 4500 for WOT and that seemed to help quite a bit. Wondering if the seafoam contributed to the dieseling because didn't have this problem earlier.
Haven't checked timing and getting ready to order Merc service manual, does anyone know the setting/rpm for adjusting the timing. Also is this a simple point and shoot procedure.
