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. ________________________________ Message 2 _____________________________________ Time: 01:33:16 AM PST US From: Alan Burrill Subject: Re: Europa-List: Throttle Stops 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" Alan #0303 On 30 May 2013, at 09:22, Carl Pattinson wrote: > 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.

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.

To have to sell G-KIMM is indeed a rotten thing to have to consider. Our best wishes to you.

Despite having removed the brushes and cleaned 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. > > A short test flight showed the propeller and all light indications to be functioning perfectly with not a hint of the FEATHER light illuminating! > > -------- > Gordon Grant > > G-BWFH > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=401522#401522 > > > > > > > > > > ________________________________ Message 6 _____________________________________ Time: 02:33:37 PM PST US Subject: Europa-List: Classic Centre Console From: "spcialeffects" 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?
