I'm cleaning up and inspecting the original (non-electronic) distributor for re-installation in my freshly rebuilt 79 12a motor. I'd like to replace all of the wear parts but ran into a couple issues. You help is appreciated.

It appears to have 4 condensers (two to the right of the vacuum actuators and two directly beneath them.) However, I seem to only find listings for 2 condensers. Clues?

One part listing I found indicated that the trailing and leading points are not the same. Mine look identical. Which is correct?

The distributor appears to be in good nick. Anything specific to look for?

First time installing a dizzy in a rotary. My factory manual only says to line up the markings at the base of the dist shaft for installation. What position does the engine need to be in? I've sen piston distributors installed 180 out. Wasn't pretty. I assume that's not good in a rotary either.

Thanks,

Herb

 

There are two painted marks on the main engine pulley. I belive the leading one gets aligned with the pointer on the front cover.

 

i believe the points are the same L and T. my 79 also had like 3 condensers on the distributor, but only connectors on the harness for 2, so i'm not sure why. mine had some aftermarket rebuilt distributor in it, so i think they might have just built it wrong.

the big wear part, besides the points is the breaker plate they sit on, it actually pivots on a bearing, which wears out. sloppy breaker plate = wandering timing

 

The points are the same.

When I put mine in I just line up the little dot on the disty shaft to the little dot on the gear on the distributer. Then put the engine at tdc (little notches on the crank line up to the steel pin). Stick the distributer in and turn it till the points just start to open. 90% of the time that puts it in perfect timing.

Make sure to duble a little grease on the disty shaft when you put in the new points. LUBE
