I've heard of the water trick...Back in the day, we used to dribble 
automatic transmission fluid down the carb to solve similar 
problems.  Wonderfully thick clouds of smoke ensued.

More recently (late 70s) when I was a Schmieraffe at a VW dealer, we 
used to use Army surplus gun-cleaning fluid to solve single-cylinder 
low compression problems in water-cooled cars.  If you had three good 
and one around 80 or so, you would disconnect the coil and put a 
squirt of fluid in that cylinder, then turn the engine over for a 
minute or so.  90% of the time, it would come right up near the rest.

Of course, I wouldn't recommend ~any~ of these tricks today.  Plenty 
of things to go wrong, and it's a lot harder to fix when it does.  I 
do recall an approved method of decoking with a wooden scraper on the 
pistons in situ.

YMMV...
