blodi Posted July 16, 2019 Author Share #433 Posted July 16, 2019 (edited) Is this play “normal” in the dizzy? IMG_3974 by blodi, on Flickr Edited July 16, 2019 by blodi Link to comment Share on other sites More sharing options...
Patcon Posted July 16, 2019 Share #434 Posted July 16, 2019 couldn't watch the video. The play bar moves with sound but no video. I have used a match box dizzy with the standard tach. Link to comment Share on other sites More sharing options...

240260280 Posted July 16, 2019 Share #436 Posted July 16, 2019 (edited) Some thoughts: Is the point-gap adjusting screw(below) turned to hold the sensor off the rotor? Is the sensor too close to the rotor? Did you inspect and lube the springs and breaker plate under the top pieces? Are all screws snug?

Patcon Posted July 16, 2019 Share #437 Posted July 16, 2019 That looks like the vacuum advance movement Link to comment Share on other sites More sharing options...

Any idea on the gap setting? I just installed a pertronix like a month ago on another car of mine, but probably didn't save the little clear "feeler gauge" they send with it.

240260280 Posted July 16, 2019 Share #439 Posted July 16, 2019 Pertronix gap is 0.85mm from the net. Link to comment Share on other sites More sharing options...
blodi Posted July 17, 2019 Author Share #440 Posted July 17, 2019 Ok. So the sensor to rotor gap is tiny...less than half what it should be. I see no way of adjusting it either on this setup. The two counter sunk screws hold the pertronix into position and there is nothing slotted to allow adjustment. I can just use one of the screws and that way angle it to adjust the gap.

240260280 Posted July 17, 2019 Share #441 Posted July 17, 2019 This screw should adjust gap: Link to comment Share on other sites More sharing options...
blodi Posted July 17, 2019 Author Share #442 Posted July 17, 2019 Yeah, but the two other countersunk screws prevent the plate from moving at all. Its' fixed in position by those two. I removed one of them and adjusted the gap. I'll see how it runs Friday as I'm bring the car in for a car show here at work. Link to comment Share on other sites More sharing options...
240260280 Posted July 17, 2019 Share #443 Posted July 17, 2019 The screw is actually an eccentric and pushes the pick-up out. Give it a twirl with a flat head screw driver and it will immediately make sense ? Link to comment Share on other sites More sharing options...
blodi Posted July 17, 2019 Author Share #444 Posted July 17, 2019 (edited) OK, I marked this up so its a bit more clear... Dizzy by blodi, on Flickr 1 and 2 hold the pertronix plate (4) to the dizzy plate (6) and it cannot move around from there. I can move 3 around a bit, but it can't move 4 at all. 5 is fixed to 4 with rivets. 7 and 8 both did need to be snugged down a bit. What I did last night is removed 1, adjusted the gap and tightened down 2. Not sure if it will hold in position with just #2 in place, but it allowed me to open the gap.
