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.

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.

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.

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. -----Original Message----- From: owner-rv-list-server@matronics.com [mailto:owner-rv-list-server@matronics.com] On Behalf Of Scott Jackson Subject: Re: RV-List: Fw: engine problem --> RV-List message posted by: "Scott Jackson" Thanks to all of you for the valuable input.

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.

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, Michael Wynn RV-8, Empennage San Ramon, California
