'84 desmogged FJ60. I am replacing my non-functioning vacuum advancer with a working one I got from @4Cruisers. Got the old one out but before I put the new one in, I wanted to make sure the breaker plate assembly moved properly. To test this I was just pulling back on the pin the advancer arm connects to connects to to make sure it moves as it should before I put this nice clean advancer can in this vehicle. Mine does not move every much so I am trying to figure out if there is something wrong with its movement (which may explain why the advancer pot went bad in the first place), or if the way its moving is normal movement with the truck off. Attached is a video I took of its movement:
Not the greatest vid but I think shows basically the movement. I am not sure if the breaker plate can only move when the distributor is spinning, if they simply don't need to move very much, or there is something wrong with mine. I know a proper rebuild/recurve is in order most likely to get this right but just am right now trying to determine if my distributor is moving properly. How much is the breaker plate supposed to rotate? Based on testing the new vacuum advance can, which moves quite a bit, it seems like the plate should move more than can be seen in the video.
FSM has this to say regarding the plate movement:
Thanks in advance for any guidance here.
