Dan,Not sure which carburetor you're running, but my experience of having owned a ModelA, along with a lot of experience with engines and carburetors in general,leads me to believe the issue is in carburetion. In general, a mixture that becomes slightly rich will make the engine run rough,where a lean mixture will make the engine produce a light exhaust popping sound(or in my 40-ish year old memory of this, it the other way around?). Are you able to pull a plug immediately after landing to see what the color ofthe electrode is? For a rich mixture it will be black to sooty, for lean itwill be gray to white, and for close to stoichiometric, it will be chocolateyin color. Due to the nature of "coloring" the plug, it may take several minutesof continued operation under the condition you experience to produce a visibleresult on the plug... and an inexact or short run could be misleading.Hope this helps.--------Tom KreinerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Re: Pietenpol-List: Re: Rib drawing

Dan,Recently, I had the opportunity to fly Allen Rudolph's old Piet, now owned by FrankPavliga. Quite a flying machine! At Brodhead it was refitted with the enginethat used to be in Jack McCarthy's Piet. When I throttled back I seemedto remember some light popping and sputtering that seemed to continue throughfinal. In fact, I noticed it enough to ask Frank and Andrew King about it afterlanding. Neither seemed to be very concerned. I know Andrew watches thislist, so maybe he'll chime in. By the way, I really think if I were to build another Piet I'd do my best to replicateTHAT one. What a beautiful flying airplane!

The Model A will sometimes make a fluttering sound on final, maybe due to someof the things mentioned above, airflow driving the prop etc. As long as it idleswell on the ground I don't think it should be a problem, hard to really judgewithout hearing it, but that is what I would lean towards.-Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: The purist and seat belts
