[T3] MPS observations

[Bobsnotch@aol.com]

Another one of those "while at the FI tech session" things. Jim had a MPS all 
apart, so we could see the cracked diaphram. So this evening I thought I'd 
take my "C" mps apart that wouldn't hold vacuum (to see how it cracked). Turns 
out the copper diaphram was still good, and the "O" ring was dried out. I also 
took apart one of my t-4 E units, and was surprised to find that the diaphram 
was actually stainless steel. :O I think it had been rebuilt, as there were no 
part numbers on it, but it did have the full throttle enrichment switch 
inside. I took apart a second t-4 E unit, and it had a copper diaphram in it. So 
was the stainless steel one a replacement part? Or a Bosch upgrade? Or someones 
attempt at a replacement? It's very nicely made, and is very thin, like the 
copper plates. Just curious if anyones run into this.
