The RPM is usually stamped in the name plate on the inj. pump.
If its a RoosaMaster or CAV it'll be on the side..
if its a Bosch IN-LINE it'll be on the back side of the governor.
If its a Bosch ROTORY it'll be on the side.

The max revs on a 850B with no load would be 2200 rpm.
Have you sorted the hose issue? Removed the hoses & not marked them?
