Hi Dave
Best wishes on your venture with Europa!
As far as a major benefit to the Europa community goes, and a suggestion if I may:
WE NEED NEV BACK!!!!
He has been a tremendous help to our XS build, taking time to answer my questions
(VAST SUM OF!---), many of which when he was off payroll. Dedication well beyond
the call of duty.
His knowledge base, talent and practical approach to problem resolution I am sure
would be a tremendous asset to you.
My vote is cast.
Sincerely
Ron Parigoris

I have had a problem of the engine surging. It began abruptly. The
previous flights were normal. I am at 500 hours without engine
problems. Now, when I advance the throttle the last one inch(turbo
comes in) the engine starts drops RPM even to the range of 3000. If I
advance the throttle up to about 5500 it runs smoothly, but beyond that
it starts to surge and will continue varying from 3000 to 4000. I have
ruled out any problem with the Airmaster Prop. The surging is too fast
for it to be the prop changing pitch. I talked with Lockwood and they
suggested the carbs need to be overhauled. They suggested the fuel
pumps might be clogged, but checked that and it runs the same pressure
it has for 500 hours. The turbo waste gate cycles correctly(I
think)when turning on the master switch and the turbo spins freely.
does the carb need overhauling or cleaning at 500 hours? Anyone had
this problem?

Ken, yes the carbs need cleaning and overhauling on a regular basis. My
experience with my 914 is about every 300 hours. You're fortunate
you've made it to 500 hours. I took my plane to Kerry at Lockwood and
he did the overhaul in about 2 hours. The price was reasonable and the
engine ran beautifully afterward. What happens is that the carbs
accumulate something they call "snot", which looks like it sounds.
Causes all sorts of problems.
Best of luck,
Garry Stout

Hi Folks,
Could I offer a contrary view? I got to 600 hours on my 914 with no
sign off issues wih the carbs, but on the adivce of many I sent my
carbs into Lockwood to have them overhauled. What a mistake, the
airplane now uses .3 to .4 more gallons per hour than before and it
took me 4 tries to get the inlet system sealed up again so I could get
maximum boost.
Actually it still is not right, I can only get 27 inches and 16k feet
and I should be able to get 34" so the darn thong is still leaking.
With that said, it may well be your carbs, but the first place I would
go is fuel filters, then look at the fuel pressure (needs to be
measured differentially), then onto the turbo waste gate. What you
will need to do is disconnect the cable and move it by hand to check
for "stickyness".
After all of the above, yep, I'd mess with the carbs.
Just my 2 cents worth.
Regards, Paul
