| Subject: | 912ULS - Rough start & Rough on one magnet |
Thank you very much for all suggestions received on how to solve the
problems I experienced.
The =93rough on one magnet=94 is now resolved, and the rough start of
cold
engine almost gone (maybe I have become paranoid and forgotten that
912ULS
always starts a little =93hard=94).
I replaced the battery with identical one ' Leoch 28 Ah. The first
cold
start (with choke) was a little rough. I let the engine run some 20
seconds
and stopped it. Restarted again with choke ' now much less roughness.
I did several stops and restarts. When the oil temp reached the
mid-30s,
smooth starts.
Carb sync solved the second problem ' some roughness on one magnet at
4 000
rpm, smooth on the other, rpm diff some 50 rpm: At 4 000 rpm the carbs
where out of sync by 1.5 cm HG ( a good =BD inch). Carb sync at this
rpm made
the roughness on one magnet go away. Rpm drop on either magnet abt 180
rpm,
rpm diff + - 0.
Before I started the engine, I pressure checked that the float valves
closed, and I inspected the carb bowls (clean). With engine on idle, I
bent, pushed and pulled on the wires to and from the electronic modules
on
top of the engine. No indication of broken or intermittent contact.
The positive effect of new battery was to be expected. The carb sync
was
suggested by the Scandinavian Rotax agent, but I must admit that I was a
little skeptical. He explained it by pointing to how the spark plugs
are
connected to the magnets on 912: Magnet A: cyl 1-2 top, cyl 3-4
bottom.
Magnet B: cyl 1-2 bottom, cyl 3-4 top (#1 is right forward, 2 left
forward,
3 right aft, 4 left aft). ) 914 has all 4 tops on one magnet, all 4
bottoms on the other. I still cannot explain why carb sync should
matter
during mag check, but it certainly does.
Regards,
Svein

Hi Nev
Have you got a picture of this pipe you could post? Also what it the
weight?
Thanks
Pete

Right, update;
I gave up on the three manufacturers I asked to bid on before, no
wonder all the work is going to China !
Found someone [ a mate] to do the job, I need to know is how many are
interested in this first batch.
I intend to keep a bunch in stock later, as ALL Classic Europa's are
going to need one sooner or later, I have inspected 3 recently for
Permit Renewal, all getting close to being too far gone.
Europa are not going to get any more rubber hoses made.
The pipes will be from 6023 [ heat treated to T3 condition after
bending in the T 0 state] with rolled beads on each end. Tags on both
ends to ground [ earth] to filler cap and ground circuit.
Will be a ''new'' Mod with the LAA as we can't use Franks Mod if there
is the SLIGHTEST deviation.Frank used 6063 T6 [ YES T6 !] How did he
bend that ? So different material spec needs a new Mod ! ?
Will be a complete Kit with all connecting hoses, clips, wire etc.....
I will have a firm price in a week or so, best guess at the moment for
the pipe only is about =A3115 / =A3120, but that depends on the number ?
Looking at the cost of the other items at the moment.
Best to ship [ especially to overseas] in multiples, as they will be
big [ odd shape] can't be folded up like the rubber ones were ! ? [
mind, I expect Maureen would have tried !]
So, who wants one in about 3 to 4 weeks ?
I have had a pipe made from gash steel to trial fit, [ got 3 Europa's
to check with, all slightly different !] if / when I get the go ahead
from enough of you I will be ready to do sets for real in the alloy.
Looks like a win / win situation going to alloy, wont get the stink
through the poor quality rubber, and it will be lighter. Also got a
''cunning plan'' to aid faster filling, will report back on that later.
So Guys, show me your money !
Nev

I started conversations with 3 potential manufactures a while back,
confess I have let it slip, will look back into it this week and report
back.
Cheers,
Nev.

Subject: Europa-List: batch of classic fuel filler pipes being made
am thinking of getting a batch of aluminum fuel filler pipes made for
the classic to replace the rubber trunk. Frank Mycroft sent me a drawing
and has had the mod approved ( it may be with Ian as well). a) does
anyone else want one making, they would be cheaper in a batchb) I can
enquire locally but pointers as to where they could be made in the UK
would be helpful (50mm x 1.5 pipe) Regards Graeme --------Graeme

In the belief or at least hope that the summer must arrive
some time, I am rearranging the Le Touquet trip for Sat 18
August. This will be the first weekend following the
finish of the Olympics flying restrictions, so if the sun
is out the sky will no doubt be fairly busy! Anyone
interested please get in touch with me.
