Default points.... here is what I was thinking.

This set I see on ebay has a notch.

I guess I can cut a notch with a hacksaw in the existing set and put them back on the machine and see if adjusting works that way.
The way they are now, there is no easy way to move them incrementally to get fine adjustment of the gap.

may be I am seeing things but the points in the pic have a notch for adjusting and it appears there is a place for a eccentric screw for adjustment

I ended up making a little notch in the side of the bass and reinstalled them... got it pretty close to .020. Hard to get it exact.

Make sure the points are not pitted when and if you use a feeler gage to set the gap.

I forgot to look when I had them off, so I shined a bright light and used a real intense magnifier and looked in there and they look okay to me... Flat and smooth.

Default reinstalling shrouds....

Put the starter back on today.

Then, I started to put the sheet metal shrouds back around the cylinders.

Didn't get far doing that. I see I should have put the shrouds on THEN put the starter back on.
It's difficult bolting the starter back in place, but it's impossible to get the initial 3 pieces around the cylinders with the starter in place. Main reason is that the large multi-sided shroud that goes around the back of the cylinder and drops down between the starter and the block makes it hard to get the two small end pieces of shroud put on.. what with the little springs that hold them in place.
I forgot how hard it was to get those off in the first place.
That rear shroud thing makes it difficult to do the starter bolts.


Wondering out loud here... there is no way to leave all this vacuflow shroud stuff off the machine and have it cool itself correctly, is there?

I'd have to come up with a whole different set up.... like off one of the other type of forced cooled generators... right?
