Paul,
       We all would miss you, please de-gunk that engine of yours. Self interest
lies at the bottom of this as I am looking forward to recieving the newsletter
for some considerable time to come!
   The discussion on water/alchohol took a tangent to power/performance rather
than carbon/reliability. From my limited experience (early 70's) SMALL amonts of
water improved the carbon build up problem, can't say about other effects in
terms of reliability,insufficient data.
    Back in the 60's when I was a mere callow youth and besotted by motorcycles
(U.K. days), I found runing the engine up to opperating temp, removing plugs and
putting a tablespoon of upper cylinder lube down each bore, leaving overnight
and starting next day-----no problems.
I think I can lay claim to making a substantial contribution to the pea soup
London fogs though!
Regards, as always

Nay! Nothing to worry about. NA rotaries give plenty of warning before they
die. Not like a Continental that jerks a piston out of the cylinder and blows
it out through the crankcase and cowl taking at least one magneto with it :-) 

I just heard a rumor that there is yet another AD out on my O-470 engine crank.
That would make number three before I got the engine completely in the
airplane and ran it yet alone fly it.
