I recently installed a rebuilt injection pump on my 656D. The
timing is set at 3 degrees per the manual. The tractor starts and
idles as it should with no issues. When I advance to about 1/2
throttle I start to get white smoke (unburnt fuel) from one
cylinder. I did not have this issue with the old pump. Is the new
pump to much pressure for the old injectors? Should one also
install new injectors with a new pump? I also considered that
bad valve could cause this but did not have this issue with the
old pump.
Thanks in advance.
