Hmm, bubble method didn't work so well. The stream of bubbles never came
to a complete stop, but there was a distinct reduction. Initially that
drop-off was at about 19° BTDC. Ah hah! The IP timing was too retarded,
if the start of delivery is supposed to be 24° BTDC for an OM603, same as
the OM617.
I checked with the locking tool method to validate, and found that to be
over 16° ATDC. FSM says it should be 15° ATDC, +/- 1°.
I didn't want to set the timing using the bubble method due to the lack of
a clear cut-off in the bubble stream and the disparity versus the locking
tool method, so I set the IP to ~21° BTDC (start of delivery) by bubble
method, which was about 13.5° ATDC by locking tool.
Rebuilt all the delivery valves, Lubro Moly Diesel Purge treatment, put it
all together and clean up, then test.
0-60 time improved from 13s to 12.25s, and less smoke.
