I have a Lightspeed Plasma II (right side) with a Slick mag (impulse coupled, left side) on an IO-320. When timing with a strobe light, the manual shows two specs - one with the manifold pressure connected, the other with the manifold pressure disconnected. My question is do I need to plug (block) the connection at the engine side when the manifold pressure line is disconnected or will the engine run smoothly (at idle) with the line disconnected?
As always, thanks in advance for direction/explanation on this.
