Vic - I used to pour water down my '74 van's Weber carb whilst revving
the hell out of it to break up gunk on the valves/in the combustion
chamber.  Once I got this water-cooled, FI, bastardized VW, though, it
just wouldn't work!

Did find out that, every six months, squirting 1-2 fifths of Everclear
($12.70/fifth locally) through the quick-connect nipple my mechanic
installed on the throttle valve housing on my '85 whilst revving the
hell out it seems to have much better results than water in the old
air-cooled!  Great clouds of particulate stuff flies out the exhaust,
the van runs much better afterwards and I can stand 15-20 behind the van
and feel those neat exhaust gas "pulses" in my face.

Once a year, I dump a quart of kerosene into the sump and run it about
100 miles up and down the highway at high speed and then change the oil
& filter.  The filter averages about 10oz more in weight than during
normal oil changes.
