Does anyone know of an effective test in order to determine if a power valve is working or not?
I am aware there are two elements to the power valve system : the valve itself and; the vacuum piston/plunger and spring assembly that operates it.
I have an excessivley rich mixture on a 1400 carb (23/27 venturies) with standard jets. Fuel level in the bowl is OK. Has a performance cam.
I firstly want to see if the valve itself is sealing before I start working on assessing the operation of the vacuum piston and the effect of the cam on the manifold vacuum and whether or not it is kicking in too early etc.
Any tips?
