#43 and #45 on this diagram. #43 is easy, that’s pressure line for the gas can which I’m not using. I’m using an external pump so I don’t need the pressure from #43, but I also don’t need it spitting air-fuel mix everywhere. Can I just connect the two?

July 29, 2021 at 9:11 am #243850I’m confused, why are there two nipples on the intake manifold? Is one of them for the cut out switch??
July 29, 2021 at 9:31 am #243852possibly… a vacum is needed … I modified my comment o the air pressure nipple

On the 1954 motors there is a vacuum switch that shorts one set of points if the motor “runs away” in neutral. I think the 1955 motors had one also.

July 29, 2021 at 1:23 pm #243882What vacuum switch?
This one. The motor will run just fine without it but it is there to prevent a runaway situation.
July 29, 2021 at 1:35 pm #243888Ahh. Is a runaway condition in these something you have to worry about regularly?
