Now, I didn't say "stick the garden hose in the carb and turn on the
water". If the engine is running say 2500 rpm, it can easily slurp down =
a
dribble of water out with just a slight stumble. To lock it up
hydraulically, you'd have to be putting a ton of water into the carb. Li=

I said, dribble. (:->) Don't dump (:-<) And keep it reved up. If it
starts to stall, or stumble badly, just stop pouring. And let the engi=

clear it self out. Some of you probably remember that in the late 70's
water injection systems were being sold as a possible solution to running=
poor quality gas in high compression cars. I had and still have a car
with a 350 chevy with 11.5 to 1 compression. So I bought and installed
one of these water injection kits and used it quite a bit. It did work,
but what they didn't tell me was that injecting water, while it does keep=
the engine from pinging, it also substantially lowers the max horsepower
output when water is being injected. =
I understand that some of the big airplane engines in WWII were equipped
with water injection systems so they could get off the runway while using=
lower quality gas. So dumping water into the carb while reving it up is
really nothing new. Just don't use a hose!
