Of course, the answer is fuel injection - there's a perfect bit of kit out
there, made by Weber, as used on Ducati m/cs etc - fully programmable (but
you need the bit of kit and software to do it) see:

It puzzles me too. It's certainly constant vacuum, the spring restrains the
diaphragm until enough force is created by the vacuum to compress it. The
force is pressure X area so it's proportional to pressure, area being constant.
Fuel is pushed through by the ambient pressure on the carb float chamber,
so that will decrease with altitude , Seems to me it will be partly
compensating for the altitude but not completely. Still scratching my head!

Thanks for the kind words Jim! Might try and make SnF next year so I'll
see you then, take care.

Indeed. For its O-320 engine, Lycoming graphs various stuff vs. mixture control
setting. EGT varies by 350 F-degrees, between full rich and the bottom edge
of best-economy range. However, % of power change in this range of mixture setting
is only a few %. However, fuel consumption varies a lot.

Mike,
With the rudder cables terminating at the bell crank, there is a
position for the push pull tube to operate the rudder. Also there are
two positions for attaching the cables for the tail wheel at each end of
the bell crank. I installed my springs and turnbuckles inside the
fuselage so that only the cables exited to bottom of the fuselage. It
looks good and reduces drag by having all the junk inside the fuselage.
I welded the "new" horn on the tail wheel and cut off the old tabs that
extended beyond the edges of the new horn. I could send you a pix of the
tail wheel to show you what it looks like if you want. By the way, you
should have a large opening in that area so you can get your hands in
there to do what need to be done. I have a 6" cover over a 5" opening in
that area. If I were to do it again, I would make a 7" cover over a 6"
hole. Mine works but I had to trim away most of the flange that was not
supporting the blind nuts. Just put 4 additional layers of bid on the
inside for about two inches around the opening to strengthen the area.
It makes maintenance in that area easy. You could make two openings - one
on each side- about 5" cover with a 4" opening so you could get one hand
in each opening to work inside. Either works. Even if it just looks
nice, I would do it. Graham did a good job engineering it.

Has anyone ever fitted fuel injection to a Rotax?

| Subject: | Bing carburettor, altitude compensation discussion |
--> Europa-List message posted by: John & Paddy Wigney <johnwigney@worldnet.att.net>
Perhaps I could add some of my observations to this discussion. I have
recently done some checks at various altitudes and can report the
following :-
All results were done on the same flight and are at 5,500 rpm, at full
throttle and the heights are pressure altitudes. The engine is a 912S
and I have the data to prove that my fuel flow meter is accurate.
2,500 ft, OAT = 13 degC, 6.6 US gal/hr.
5,000 ft, OAT = 9.5 degC, 6.2 US gal/hr.
10,000 ft, OAT = 7 degC, 5.5 US gal/hr.
I did not note the EGTs but will check these next time out.
I do not have any technical info on the Bing carb but it appears to me
that the fuel flow rate is certainly being adjusted with altitude. This
is consistent with my understanding of how the similar SU carburettor
works with the free floating piston and tapered needle being positioned
according to the pressure in the carburettor throat. If the absolute
pressure in the throat at full throttle is lower due to increased
altitude/reduced density, the tapered needle will be lower in the jet
and the fuel rate will decrease accordingly.

Dear Listers,
Pacbell is suppose to be working the Matronics connectivity issue this
morning. Intermittent connectivity is still a issue although things are
better than yesterday. They will probably be doing some intrusive testing
on the line later today which will disrupt connections during the test.
More information as it becomes available!
Thanks for your patience.

Well, only 497 unread emails in my Forum folder left to read. It's been a
bit busy the last month or two, so apologies for taking longer than expected
for resurrecting the Europa Club Web Site. If it's any consolation, the last
date in my build log for G-EZZA is 19th November :-(.
The Site is now live again, apart from the password-protected members-only
section. We are working on that and hope to have it live shortly. Now we
have sorted out the problems (by the 'simple' expedient of moving ISP!) I
can start updating the site again, so this will be done over Xmas.
Many thanks to Rowland Carson for his unstinting hard work, and to Jos
Okhuijsen for his kind offer to host the site for the Club. The site would
not have been back up as quickly without their help.
Finally, I'd like to wish everyone a very wonderful Christmas and New Year!
Regards,
Jeremy
