Hello, All:
Where do those of you with Combi drives have the "Neutral" position for the
system: is the lever vertical, or about 30 degrees forward of vertical for
neutral?
Just now I have VESPER (V1868) hauled and propped because of Combi / engine
problems. Before hauling, the engine would fail as follows: While tied firmly
to the dock, I would get plenty of 'prop-wash' while in reverse, but very
little while in forward. Also, when going forward or reverse, the engine would
accelerate sluggishly, then, without any action by me, would pump out lots of
smoke and slow down, then surge and slow down again, etc.
The coordination between the prop-angle, throttle position, engine speed cam
and whatever else, just is not set correctly. Steve Birch suggested that the
prop setting may be off, and I believe it is. Thanks for that, Steve.
Now though, how do I go about getting all these things adjusted in proper
coordination with each other? Is there a sequence for setting them? Here's the
biggest question of all: could the prop itself being at incorrect angle cause
this strange action by the engine? Even the surging and the smoke?
What else in the engine - or the rest of the system is there to check, now,
while high-and-dry?
Thanks in advance for any suggestions from others who have had this problem
and have solved it.
