Then you haven't tested, but one. ;-) It's a rubber like diaphragm,
and needs to be replace about as often as wiper blades. Test for leaks
by pulling the vacuum hose, collapsing it and holding your finger over
the hole.

I guess I have been lucky, because I test every one by sucking on the
hose.

soooooo ... did you find the loose intake manifold gasket yet? the late
valve timing? the holes in your vacuum lines? etc. ? ;-)

Nope, the pinching the line did not affect the idle. This is the line that goes
to the pair of vacuum canisters on the right (passenger) wheel house (just
behind the battery). I tried removing the line and making /sure/ it was plugged
and it did not affect the idle.

Is there a vacuum diagram for this online somewhere? Or, which manual does the
'least worst' job of correctly charting out what goes where. It all looks
correct.

Pardon my ignorance here, emission control systems are not my forte.

Then the question becomes the best price for a rebuilt one. Carb Exchange is
quoting $289 for one, is that a in the range of reasonable for a replacment
remanufactured unit? I'll get a kit this weekend and give it a try (they'll
take my failed rebuild as a core) so it'd only be the cost of the kit wasted.

Ok, then too high a vacuum on the float bowl isn't an issue.

Go for the kit, you should be pleasantly surprised.

Also check that choke pull off like others have mentioned, I just suck
on the hose to see if it holds vacuum, but your symptoms point to a bad
float needle and seat and worn gaskets.

Turning and dying, is float usually, it either sticks open or closed,
both stop the engine.

I did see some messages (stfw, google) on there being problems with too low a
vacuum level not being able to 'run' the necessary bits. So I'll be digging out
my vacuum gauge tomorrow to measure what it's pulling. Any suggestions on what
take-off point to use for measuring?

> Go for the kit, you should be pleasantly surprised.

I'm hoping if I make a mess of it the remanufacturing place won't care. So if
my rebuilding fails I'll only be out the cost of the kit and my
time/aggravation.

Yeah, the odd thing it would only do this when making a left-turn at speeds
above 15 mph or so. There had to be some weight-transition movement to trigger
the stall. This was on the old 2.8L via mechanical fuel pump as well as on the
replacement 3.4L with it's electric pump. So I'm not inclined to think it's
fuel pressure related but I've never measured the pump's output.

How much of the linkage and such am I going to have to disrupt to do the
rebuild? Can I hope to be able to maintain the various bits of alignment that
exist or am I going to have to set it all up from scratch again?

Does anyone's carb book /really/ do a good job covering the 2SE? (I have a 2SE,
not the E2SE, thankfully)
