Throttle adjusting screw (049 133 432)

[isham-research.freeserve.co.uk at pop.pol.net.uk]

I've been measuring the O-ring as carefully as I can.

I make it ID = 5.3mm, OD = 9.3mm, thickness 2mm.

Anyone else measured one and care to agree/disagree?  I'm trying to
set up a proper supply, as with wastegate diaphragms.
