Can a Vetus Waterlock Muffler fill with engine exhaust debris (Soot/Oil/Crap) and cause the engine to loose RPM's when under load? My Universal 5614 will not go any higher than 2000 rpm's and when its up there I see black sludge like in the exhaust water. It's not like real smoke, more like faint black coloring mixed in with the exhaust water. I've checked the Air Filter and intake manifold. I've cleaned it well before re installing. I removed the exhaust manifold, the mixing elbow and cleaned it all up (not that it really needed it}. The flexible connector from the mixing elbow to the Vetus box is clear as well.
My next step is to install new fuel injectors. I have the new ones, Denso brand. Just waiting for the copper washers to arrive. While I wait, I have been mulling over any other possibilities. Any help is always appreciated.
PS (my stuffing box is loose enough and is not binding the shaft. The transmission fluid is clean and topped up to the fill line.)
