F4 Voit Corsairs used water injection. It was not to be used all the time
just when a ZERO was on your 6

Yeah, water injection. Didn't passenger jets use water injection during
take-off for increased power? I also seem to remember J.C. Whitney selling
something like a water injection system for increased power (and fuel
mileage?) back in the 60's. It was one of their "wiz-bang,
plastic-fantastic, gadgets of the month".

The water trick is what I watched my mechanic friend do in the first weeks I
owned Bev- except it wasn't sprinkled in- we actually poured over 2 litres
(half gallon) through the carb throat over the course of about 90 seconds.
As long as the revs were kept up, it didn't stall, and the black & white
smoke from the tail pipe, he said, was the soot and steam, depending on
whether the engine happened to be revving high or low at that moment.
This cleared up a nagging run-on problem which, he said was due to
superheated (glowing) carbon deposits in the chambers. Of course, all
disclaimers apply.

..another method (although I am sure some will balk at it) is to
sprinkle/sprits
water down the throat of the carb while the engine is at operating temp. and
running.
...be careful if you do it this way.... too much water too quickly stalls
the engine
and can possibly cool the engine components too quickly.
But at the same time this is what breaks the carbon loose. The warm metal,
vs the sudden cooling effect
on the carbon from the water, cracks it and it blows off.
(as usual... no warranty expressed or implied... YMMV my $.02..)
