MPS, Rebuilding the MPS Options

[Ron914]

Hello to all who have helped me with this project . @emerygt350 ,@TJB/914, @Superhawk996 , @ChrisFoley , @rjames , @MDTerp
I am in the middle of rebuilding my MPS and have a couple of comments and questions .
First when I opened up the unit I found the most difficult job was removing the rivets holding the two halves together.
When I removed the retainer plate to take out the old diaphragm it was in two pieces .

I needed to take two measurements since I was replacing the stop screw , I needed to measure the the stop screw protrusion into the housing . The instruction sheet sent to me by a member had the measurements he must have made when rebuilding his MPS . His stop screw protrusion was 1.97mm and mine only measured 1.72mm.
His inner/outer screw assembly depth in the old diaphragm measured 6.51mm .
Here's one of my questions ?
when I measured mine I got two measurements depth to inner/outer screw assembly was 4.03
and depth to the washer outside the inner/outer screw assembly was 5.46mm.
Again there is a difference and since mine was never accessed before (epoxy over screw was not disturbed) is the difference in measurements ok and which measurement should I use I will try to attach a photo or two to help with my question.
this one .

I have not touched either of these measurements yet and awaiting any help/comments.
I think it's this one to the washer on diaphragm .

I think that is exactly what I did the first time too. While you have it out, map the curve. I sent you some emails describing how...

Hi emery , I checked all my email boxes and I never received the email , unless that information is in one of the three emails sent 5/9 .

Yep, that's where it's at. And seriously, your mps is leaking down so slowly I really wouldn't sweat it. Your engine is going to be pulling vacuum continuously. There is no way it will cause any affect on the djets performance. Get the curve done and post it. Tomorrow I will let you know how deep into my mps the inner screw and outer screw is at 0 and 20. That will potentially give you a sense of how far off you may be. Each motor and mps is going to be different, but not that different. Very small changes (1/4 turn) on that inner screw have a big effect.
