removing fluid from cylinders(3B.)

Now, I'm trying the DSM-list procedure for decarbonizing and it's working
great.  First I do the part where you inject the Mopar Combustion Chamber
cleaner into a vacuum line to the manifold w/ the car running.  Super.

Now I do the "spray it in the spark plug holes and let it 
sit" part.  Seems to be working wonders(see next.)

So, I confidently plop a towel over the holes to keep the stuff from
spraying everywhere, disconnect the ignition module, and turn the engine
over.  The cloth bounces up and down(very amusing to watch.)  After a few
seconds, I stop and get out, inspect the cloth...5 very dark brown soaking
spots with -lots- of carbon bits and dirt all over.  Great!  It worked!

So, I do a little double checking with the old flashlight(equipped with
fibre extension.)  Hmm.  There's still liquid in there.  That's not good.

Seems that the engine doesn't have quite enough oompf to get all of the
liquid all the way up the rather deep holes on the 3B engine.  Ooops.

So, after several 5-10 second starter runs, there's still a decent amount
of the stuff in each cylinder.  Nasty browish, carbon-chunk-laden
soup.  Tough to guess how much, but it appears to be about an eigth of an
inch "deep."

I've tried, without much luck, blowing it out with a compressed air
gun+extension tube and a bunch of other things.  I have not(given the
flamable nature of said cleaner) tried using a shop vac, with good
reason.  Also tried plugging one plug hole to "encourage" the liquid to
exit via the valves, not the cylinder hole(didn't work, I got a nifty
shop-rag-cannon.)

 Any other suggestions?  Pulling the head is -not- going to happen.  I'm
also curious to know how much fluid I need to be concerned
about; most of what I've heard and read says that it takes -very-
little water, so I'm not about to just pop the plugs in and turn it 
over.  What will probably happen is I'll simply let it drain
overnight; the fluid should seep through the rings and in the morning, the
fluid will be all gone.

But I'd like the use of the car tonight, so suggestions on accelerating
the process are fully welcomed.
