DIR and Poseidon

Finally some who knows what he's talking about. Kudos to Steve for
summing it up and setting the record straight.

Speaking of POS, look who pops up in favour of them.

Anybody need a better reason to stay clear of them?

Nope. That would have done it, if there were any questions left.

Poseidons are for strokes. He just proves that.

Re-read what I wrote... I didn't know what the problem was until I
got it open. A friend had something similar happen with his Micra and
he had unseated the diaphragm... I was thinking the same thing had
happened... I didn't think the exhaust flapper would have pulled in
between the spokes.

A spare hose costs about three times the adapter, takes up as much
room as a spare SPG, and will be junk in a few years.
The adapter is good forever under any conditions as long as you change
the O-ring, and it'll fit in a coin purse.

It was the one shown here:

I don't know, nor do I care what model it was.

Re your sig, despite the recent report, I've heard from several inside
sources that a missle shot down that flight.

Of course.

It came from a black helicopter.

You dive with spencer, don't you?
