Dear Listers,
If you received this particular Matronics List Email message, its because you haven't
yet made a Contribution to support your Lists! Implemented for the first
time last year, the Matronics system selectively sends out the Contribution
messages to those that forgot to whip out the 'ol credit card this year to support
the continued operation and upgrade of the Matronics Email Lists! Don't
you wish PBS worked that way? :-)
You heard that right. Once you make your Contribution, these support requests
messages during November will suddenly stop coming to your personal email inbox!
I wanted to implement something like this for a number of years, but it was
always such a daunting task to modify the back-end List processing code, that
I just kept putting it off. Finally last year, I just decided to bite the bullet
and put the code-pounding time it to make it work. A few days later, bam!
A working system!
I really do appreciate each and every one of your individual Contributions to support
the Lists. It is your support that enables me to upgrade the hardware
and software that are required to run a List Site like this. It also goes to
pay for the commercial-grade Internet connection and to pay the rather huge electric
bill to keep the computer gear running and the air conditioner powered
up. I run ALL of the Matronics Email List and Forums sites here locally which
allows me to control and monitor every aspect of the system for the utmost in
reliably and performance.
Your personal Contribution matters because when combined with other Listers such
as yourself, it pays the bills to keep this site up and running. I accept exactly
ZERO advertising dollars for the Matronics Lists sites. I can't stand
the pop-up ads and all other commercialism that is so prevalent on the Internet
these days and I particularly don't want to have it on my Email List site.
If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email
Lists, please make a Contribution to keep it that way!!

Hi all, At overhaul I had the cylinders flow balanced, the engine runs
very well, very smooth. Considering the rising fuel costs, I have been
considering attempting to run the engine LOP, I have been unsuccessful
as the richest cylinder peaks last and by then the other cylinders are
running rough. I use the AFP fuel injection system which performs
flawlessly and have moved nozzles around to effect egt changes which
have been effective to a point, where cyl #6 runs 100 degrees cooler
than the others. My question? Is 100 degrees a significant number when
compared to the other five cylinders?The engine builders out there who
are making real HP see the different relationships on cooling effects
and cylinder balancing and the induction system. Question #2 does cold
air induction help to make the lycoming run more evenly balanced in
respect to temps. #3 Is it possible that the stock lycoming intake
system generates to much internal turbulence which effects the
individual cylinder performance? Thanks for any info and taking the time
to answer. Bob

Have you moved the thermocouples around too, to assure that your 100
degree difference isn't due to a thermocouple difference?
