I have bought a Petronix system that will fit to my existing Autolite distributor. The kit should arrive on monday next, Having taken the dizzy out of the engine I thought I would check the advance vacuum system by sucking on the pipe in the pic.
My lungs aren't what they were but nothing seems to happen. When I try and rotate the plate that the vacuum rod is attached to its not easy to move but does move with a little pressure applied.
My question is this, is this normal?
Car ran fine previously, so I imagine it was working but I have no experience here, all help appreciated.
