yanmar L90AE_DE

[beambeam]

Hello;
I have a L90 yanmar diesel.I took the injection pump out and i can't seem to get the throttle working properly after installing it.I tried the governor in different positions but when i move the throttle open just a bit it starts revving.One of the studs holding the injection pump down is stripped. could this be the culprit.

Thank you in advance.jim
