Many of you may remember my 123 Distributor install that finally worked out.
(here: http://www.914world.com/bbs2/index.php?sho...370332&hl=)

I now have a vacuum pump and multi meter - TELL ME WHAT YOU WANT TO SEE.

Unit is an 041 and has obviously been cracked open - before my time.
It's marked with a Sharpie "74-76 2.0" which I believe is incorrect and should be for a 71-72 1.7. Maybe this accounts for the opening and potential adjustment.

Currently holds 15in pretty much indefinitely and I get 93ohms between pins 7 and 15, and 344ohms between pins 8 and 10.

All that seems pretty much right on - but it would NOT start after putting in the 123. Prior to the 123, it ran "fine" but then started running warm due to a distributor vacuum issue (more in another thread) Distributor was an 011 with a Pertronix Igniter II. Installed a "correct" 043 MPS and it fired right up and works great with the 123.

Honestly - I'm just looking to acquire some database info for the World and then move this on, so if someone wants it, just yell. I have no idea what it's worth.
