Hi, Just been trying to find cause of vacuum unit not working on my carb. On removing pipe and trying to blow through, we find it blocked. Fitted a clear tube and now solved problem. On inspecting tube have found what looks like a brass retrictor with very fine hole in middle,(which is blocked) .The tube Im using does not have "restricter". Should it?

I think I am right in saying "Yes", iirc it acts as a "damper" slowing down the movement of the diaphragm.



Waits for Kev to come along and shoot me down in flames
