The mystery burn down.........................
Water in your fuel, even 1 drop can cause a burn down. A friend of mine who
raced Formula 1 boats (outboards) made me aware of this.
Be very careful if your fuel is exposed to moisture in any form.
I have a marine fuel water seperator that I have used.

<<<IF YOU ARE NOT CRAZY ABOUT THE JETTING THEY RUN JUST ABOUT FOREVER.>>>
Jay,
At last year's Summit Point National, I was running along with relatively
low EGTs - somewhere around the 1100-1150 range, IIRC - and had a piston
burn
through with no warning. I still have the data runs from the session where
it
happened; one side went from cold to WAY hot in about three pulses. The
jetting I was running was EXTREMELY conservative and was actually richer
than I
normally run (it was the first event of the year, and the air was pretty
heavy). After I replaced both pistons and the top-end gaskets, it ran the
rest
of they year with no issues. I never could fully explain it, but my guess
is
that there was either an intake manifold leak or a clogged jet.
At the 2004 Watkins Glen National, I had a water pump failure that ended up
burning down the engine - a total loss. Granted, an ill-timed full-course
yellow made matters worse, but....
Am I just terminally unlucky, or does this sort of thing happen to other
guys?
