[QUOTE="Pappy, post: 475965, member: 3278"] [size=5]Sorry, just getting back to this. Glad you finally clarified you were talking about the pulse line. However, the pulse line is connected to the crankcase and should have a common signal regardless of throttle angle, RPM, or load. The piston provides the "pumping" action and reed closure provides the valving for the positive and negative pulses. A pulse line, therefore, will not see a reduction in vacuum pulse at a WOT setting. Anything in front of the reeds will vary though. Are we finally talking about the same thing ? [/size] [/QUOTE]
