There is no problem with leaving the electronic fuel pump all the time. It
is designed for continuous use. If that removes the stumble, why not leave
it on? I think peace of mind would be important also to any passenger.

Scott,
There are documented engine/carb issue of this nature in the archives.
What is the
10-##### number on your carb? Past issues have concluded that certain
10-####'s
carbs have a different bowl venting scheme that, for some reason, allows a
turbulence
to occur at different airspeed/throttle setting. The turbulence appears to
cause the
engine to run lean for a very short period (100-200 milliseconds). I don't
remember
the 10-####'s that cause this, but Van supplies engines with the correct
10-#### carb....
Fred Stucklen
RV-6A N926RV
Subject: engine problem
Folks:
I've been riding the right-seat since first flight of a new RV-6
with an 0-320-E2D,
carburetted.
The engine has displayed a momentary burp-not really a miss- every
single flight
when the power is reduced from full throttle. Even flying circuits, it
will
do it at the top of every climb, as soon as the throttle is brought
back from
full.
It does not do it when power is further reduced, as in setting up
for a descent.
The engine has about nine hours since overhaul, including three
hours on the
run-in stand, but has been sitting for quite a few years. It is
equipped with
two magnetos.
It originally idled quite fast- about 800 rpm, but the idle speed
adjusting
screw was backed out until it idled around 550-600 rpm, but, after the
last landing
last week, the engine was shaking the airframe and we could see
individual
blades going by out front, it was idling so slowly, less than 300rpm.
Don't
know if this would contribute to anything, or if it indicates a
temperature-related
problem with the installation. The propellor is two-bladed wood.
Other than those two characteristics, the engine runs very well, and
puts out
lots of power for takeoff.
My first guess is something's wrong with the carburetor or its
settings. It runs
on 100LL only, and the entire firewall-forward is very traditional,
with nothing
exotic.

Thanks to all of you for the valuable input.
The only observation that I can make right now is that leaving the electric
pump on does not help, as it would doing circuits.
I find what part number that carburetor is as soon as the cowlings are
pulled.
I think we are on the right track with the need to have the carburetor
modified to a different standard.
Others have emailed me off-list to let me know that their engines do this
also, so it would be nice to track down the fix for this behaviour.
Thanks again.
Scott

Scott,
This appears to be a common problem. If it were me, I would contact Mahlon
Russell at Mattituck. He's very active in the Lycoming Yahoo group as well
as Doug R's VAF Forums. He's very knowledgeable and helpful, plus he has a
TON of experience he's willing to share. You could probably post it on the
Lycoming group and have his answer the same day.
I regularly fly a C-172 with the O-320 E2D engine and have never noticed
this problem, but am interested in what you do to eliminate your problem.

I don't have one for the RV-8 but here is how I mounted it on my RV-7.
You maybe able to get some ideas from it.

I'm new to the list and appreciate all the insight provided by everyone.
It's been very helpful in precluding some mistakes.
I inadvertently deleted the websites provided for ordering the reamers.
Would you please send the website info again?
Thanks for the help.

Good sources of aircraft tools are these guys among several others.
My first choice is always to deal with those companies who are aviation
oriented and who support the various get-togethers like Oshkosh, Arlington,
Copperstate, etc. whenever possible. If you attend some of these events, you
will often see and meet the principles in these companies. They will often
go the extra mile to meet your needs.

Hi all,
I cut, primed and riveted in my elevator stiffeners over the weekend. On
bending the skins, I found that several of the stiffeners were fractionally long.
The bend is fine but there are a couple of little waves where the ends of
the stiffeners didn't give. On more carefully reading the plans, I missed the
notes where it says to trim the ends to specified lengths.
At any rate, it is clecoed together and looks fine. Is this really okay? I
am concerned about the ends rubbing on the skin.
Regards,
