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. |

Finally got around to opening up @FlacaProductions MPS.
It ended up having the 2.0 spacer. This thing was crusty though. Also, On the 3 rebuilds I've done I've never seen the one where the outer perimeter of part of the fitting was cut this way. Maybe some looked like this though? I don't know when the unit was rebuilt, but it doesn't look like a diaphragm from Tangerine Racing was used or an OEM one. Wonder if the diaphragm came from another make of car? If it were mine and I needed an MPS or wanted to have a spare on hand, I'd probably get Tangerine's rebuild kit and give it a go. If it still ended up being flakey after a fresh rebuild, I'd try and find a cheap failed MPS and swap just the diaphragm I just bought over to it. |
