Eric,
You might check through a local Mazda RX club for a local rotary guru with a
shop...they just might be intrigued enough to give it a shot. You might
sniff around www.rx8-club.com as well. Us rotary owners are a clannish
lot....

The Schleicher factory uses a CO analyzer to tune the Wankel motor in
their self-launching gliders. I'd like to do it this way, as it gets a
good tuning more easily and quickly than the usual fiddling around with
the needle valves until everything is running right.


Isn't it possible to arrange with an automotive mechanics to do the
tuning for a small fee? Here nearly all these people have a CO analyzer.

I tried this initially, but nobody wanted a 60 foot glider assembled in
their parking lot, blowing a lot of air and dust around, nor did they feel
it was safe. I don't blame them - when you are standing 3 feet from a 5
foot propeller turning 2000+ rpm at full throttle, it really gets your
attention! They also were uneasy about doing work on an aircraft, since
they are not certified for that.

I also tried to borrow or rent one of these instruments, but the only ones
I could locate were not portable: they were part of a heavy, roll-around
cabinet that weighed over 150 pounds, contained several instruments, and
could not be conveniently taken to the airport (or anywhere). Nor did any
of the owners want to let a $4000-$5000 instrument that they depended on
for their employment leave their sight!

There are enough (25 or so) ASH 26 owners in the US that some of us could
buy a CO analyzer together, then ship it around the country as needed.
This might be only 3 or 4 times a year, as the engine doesn't need tuning
very often. Sharing ownership would cut the individual's cost to less than
$150. If we can locate a suitable instrument, that's how we'll likely
proceed.
