I seem to recall in the early days of Europa that the PFA dictated that we
should install a physical throttle stop on the throttle lever (in the
cockpit).
I have never really understood the purpose of this as the carburettors have
their own stops as IMHO one seems to fight against the other. As soon as you
increase the idle RPM using the adjuster screws on the carb, the throttle
lever is pulled forward by the cables, moving the lever away from the
cockpit stop.
We have flown quite happily with the carb stop limiting the slow running
with a gap of about 2 mm between the rear of the throttle lever and the
stop block (tufnol). However, we have just overhauled the carbs and are
resetting the balances etc so were wondering if this omission needs to be
addressed - it would just be a matter of elongating the holes in the
throttle stop.
Reading through various articles on Rotax/ Bing carburettor balancing I note
that these also stress the need for a cockpit end stop but give no
explanation as to why.
I'm sure there is a good reason, just need someone to cast some light on
this.

Carly,
=46rom the Rotax Installation Manual, Page 2-4.
"The addition of a throttle-closed stop is important to avoid the
possibility of excess tension on the throttle cable causing loss of
throttle control"

Carl,
My understanding is that if there is no throttle stop on the throttle
lever, it is possible to deform the throttle stops on the carburettors
if one pulls back too hard on the throttle lever.
Cheers

Paddy,
Very sorry to hear that your health problem has not resolved itself
satisfactorily.
To have to sell G-KIMM is indeed a rotten thing to have to consider.
Our best wishes to you.
Mike and Margaret

the slip ring once, I decided to do the whole operation again. What I found
was the inner ring brush had a very sticky spring and was sometimes getting
stuck at the mid-way point, thus making intermittent contact with the ring. (When
I removed the brushes the first time everything appeared fine so I missed
the problem.) It is possible the vibration caused by the landing run and stopping
the engine might have been enough to cause the brush to contact the inner
ring as all ground feathering tests were fine.

| Subject: | Classic Centre Console |
I am about to start on the cockpit module part of my build and would like to get as much space as possible inside so am thinking of doing the width increase, hi-top mod and would also like to change the centre tunnel for the slimmer XS one. I came across this:http://www.theeuropaclub.org/wp-content/uploads/2011/12/No-32-Dec-2001.pdf please see page 12 mod 24 and then this week came across this site http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&eotf=1&u=http%3A%2F%2Fwww.oy-raf.dk%2Fhome_dk.html . My questions are, is this a possible mod in the uk, what with the laa's rules and regs and has anyone, other then the above web site, do this mod? Thanks in advance for all advice given
