The dual point units came with 2 thrust washers and the single points only 1 so might have been a simple assembly line mistake. Take off one of the washers and reassemble it & (re)check for end play and binding

Cool, I'll give it a shot. The FSM shows 2 washers, but I didn't understand the logic of requiring 2- other than to just shim the cam to line up with the point set.

Ok- without the extra thrust washer, I can get the end play to .010 (I managed to snag the Moroso distributor washer kit so I got a few different washer thicknesses to play with) with a single washer. Is that close enough? If not, I can try using combinations of washers to see if I can get it closer...

Yes, if there's no binding and the point alignment on the cam is OK you're good

The binding's completely gone- the lower shaft turns smoothly now. As for as the cam alignment I haven't gotten around to reinstalling the mounting base and the advance plate yet but I think I'll be ok- since I'm running the Pertronix I would think it'd be a little more forgiving in that department. But I'll check to make sure that should I go back to points in the future that the rubbing block on the points set will still line up properly with the cam.

Holler if getting the dizzy squared away takes care of the stumbling. If it does not we'll keep on it

Question on reinstalling the Pertronix sensor - I've got the installation sheet and it makes no mention of setting a gap between the sensor and the magnet sleeve. Is the gap critical or would just making sure there's clearance between the magnet sleeve and sensor good enough?

my ignitor I has a plastic gauge that came with it to set the gap at .030 IIRC use platic to set the gap nothing metal.

yes it needs to be correct gap just like a stock elect dist.

I've got the plastic gauge around somewhere, but I've also got a set of brass gauges- won't those work, too?

Nuts- I was afraid you'd say that as while I know where my brass feeler gauges are, I'll have to do some hunting to find the plastic gauge. I know I have it- I just don't know where It's just as well though as during reassembly I had managed to lose one of those tiny screws that held down the wire retainer so I got to scrounge one of those up, too (and I know that's going to be fun... )

David,keep in mind that the original collar will only go on one way,the collar and shaft were drilled as a unit,if you turn the collar 180* the pin won't go in,if you can't find the correct collar let me know,I have some N.O.S. ones left.If you need anything else I have a "lot" of excess distributor parts.

I got the collar back on without any issues- right now I'm dealing with small parts that like to wander off...

And thanks for the offer on spares - I swung by both Ace Hardware and Home Depot and found some #4 and 6 machine screws that I THINK will work (hope I don't really need a #5 - noone has those...). If not, I'll PM you

Some progress- the distributor is back together again. The gap still needs adjustment and I'm still looking for my plastic gauge (I suspect it's out in the shed and I won't be able to get to that until the weekend) so the distributor hasn't been reinstalled yet.

I did slice out a 'window' on the ruined cap between two plug wire terminals to check the gap with the corrected end-play and the new rotor with the .060" longer blade and it fits great- a much smaller gap than with the original rotor, and the rotor tip misses the bases of the plug wire terminal posts by at least a 1/8". So it looks like the original problem is taken care of...

Hopefully when I find that gauge I'll be posting again this weekend to report on any changes in the engine....

Not yet , 1/8" is way too much, we want the tip up to the same height as the vertical part of the metal cap terminal and as close as .010-.015" laterally to the terminal(s) tho it will be more than that (unmodified) even with the MO 3000 rotor

I've taken pictures which I'll post tonite (I'm at work right now) - they're not the best pics, but they should be good enough.

The distance between the vertical part and the tip of the rotor is VERY small- about 1/16-1/32" (I didn't measure the gap, that's eyeballing it) But you're saying I need a bigger distance than 1/8" between the top of the tip of the rotor and the base ('base' being the horizontal flat portion) of the spark plug wire terminal?

I had understood it (my bad) that the top of the rotor tip was an 1/8" away from the bottom underside (vertical side) of the cap terminal which is too much gap. If the lateral distance is 1/16-1/32" so that the actual distance between the 2 pieces of metal is 1/16-1/32" then the vertical height of the rotor along the length of the vertical side of the cap terminal ain't important as long as it is not so high that it is hitting the top horizontle portion of the cap terminal. Sounds like we're good

I'll post the pics anyway- but I think we are good, too. There's plenty of clearance above the tip of the rotor- even if I take up all the shaft's end-play (which certainly isn't much anymore), and the horizontal clearance from the rotor tip to the vertical facing of the terminal is much better than that of the old rotor (I probably easily had 1/8" gap from the old rotor). I'm hoping to get a MUCH better spark from this than what I've been getting before.

Pic of the 'window' I sliced open in the cap:


This is the best shot I could get showing the clearance between the .060" rotor and the wire terminal. As you can see, the horizontal spacing is very close and the vertical spacing is not
