I have a Kubota ZB600 diesel engine and the
manual calls for 21-25 degrees before TDC.
We recently rebuilt it and we checked the
timing and it was about 13 degrees before
TDC. We took out the two shims that were
under the little injection pump and it is
now about 16 degrees BTDC. There are no
more shims to take out. How do I move the
timing more? As a side question, the engine
is rated at 3200 rpm, but we only run it at
about 3000 rpm. Does reducing the speed
negate some of the timing advance? In other
words, is 16 degrees now sufficient?
