Before mounting my OS 32 on the Thundertiger P51 Mount, I noticed that one of the top of the bolt mount hole's on the engine is obstructed by the remote needle valve fuel outlet, not allowing a straight shot by driver to it.

I can't see how I can get a screwdriver/hexdriver to the head of the 4/40 bolt as I have no straight shot to it.

I hope I DON'T have to remove the nipple?

What do I have to do????

Thanks, Dennis
