    951 oil injection pump

    I rebuilt a 951 and when I started her up she purred like a kitten except the oil injection pump does not appear to pump. I did do the pre-mix as recommended by the book in the gas tank.

    I pre-loaded the spring, bled the pump, and made sure it moves when the throttle moves. The oil advances really slow if at all as seen through the clear hoses that go from the pump to the carbs. I read something about using the jam nut to align the lever marks to the oil pump but did not do it.

    Do I need to do that or anything else? Anyone have a pic of these mysterious marks? What is the best way to make sure the oil pump works properly?

    I couldnt get my camera in close enough inside the hull so I snapped an old pump with the correct marks lined up.

    You have to align the marked X with the round lug marked Y when it is at i the correct idle speed. To change it undo the 10mm nuts at the carby on the oil pump cable and adjust until the shinney mark is right over the small lug and then do them up.
