Help with setting dwell on dual points
Can someone please give me the basic process for installing new dual points?

I blocked off the secondary points with a piece of paper. Primary points (with condenser attach) is set at .018 when on the flat part of the cam lobe. Tried to start car but no go. Should it have been set at max opening on lobe instead?

set the points when the lobe opens them, usually when the high point of the lobe pushes the points open. Also put a dab of grease BEHIND the contact block so that the grease will wipe along the lobes of the dist shaft. Not a lot, just a dab. Not sure if that is an english dab or a metric dab.

OK reset primary points at .018 at top of lobe. Car still will not fire, should I set the secondary and try to start with both?
Did add dab grease.
Did add dab grease.

Primary points are adjusted. Now if I am going to put a piece of paper in the primary side, in order to set the dwell on the secondary point set, what about the condenser? It is tied into the primary points does it now need to be moved to the secondary points?

Haven't touched a dual point in 40 yrs. but no leave the condenser as is. It's there to reduce the arc as points open to give the points more durability by reducing pitting. I'm thinking electrically both points are tied to the one condenser anyway.

Switched condeser to other points before I saw your post. Got it running and dwell was at 21. Needed to get to 29 to match the other points. Turned up to 25 and then mane another turn which should have put it close to 29. Went to start and now won't start. Set it back half a turn to where it was running and still won't start. Was one turn away from being done and now I have no idea what went wrong.

Pulling the feeler gauge out from between the points did exactly the same thing as the distributor opening the points- made the coil fire. That's why there is a condenser in the system. It reduces the arc when the points open. Still, getting zapped like that is a cheap thrill.

And leave the condenser alone. The points are in parallel, and it does not have to move.

OK got it running again. One side is 29.5 and the other is 28.5. Having a hard time adjusting anymore because the metal on the adjustment screws is too soft and deforming. I took the car out and runs fine and no more pinging when opening it up! Is it OK to just leave adjusted the way it is?
