Subject: Pietenpol-List: Re: Weber CarbMy guess is that there isn't enough fuel pressure. Runs fine until the carb bowl runs empty then she quits. But there must be just enought fuel/head pressure to refill the carb relatively quickly -- then she starts right up again.Any chance the fuel filter is partially plugged, or fuel line? Could possibly bean electric component in the ignition that is heating up and then opens the circuit -- but I imagine you have a magneto. Sounds like fuel starvation to me...FWIW. Been working on my Piet's landing gear struts and metal fittings. With this nice spring weather I sure wish it were finished -- couple years yet, though, unless I win the Powerball or some other lottery. Then it won't be a case of building faster than budget allows...! Fred B.________________________________________________________________________________

Dale Johnson and I had the same problem. Engine would start and run fine but thefuel bowl would empty out. The problem was an air-bound fuel line.The fix was easy. Just lift the tail as high as possible for a minute or so untilthe air bubble worked it's way back up to the tank.No problems after that.Greg Cardinal----- Original Message -----

Agree with Fred re: fuel pressure, as possible problem. I put an O-235 on N-1033B,while testing with only a couple gal. fuel, the carb acted starved. Thisengine was designed for planes with fuel tanks in the wings, therefore a couplelbs of headpressure. The tank behind the firewall on the Piete seems tome to be too low to maintain much head pressure while the engine is sucking fuelat higher RPMs. I put on a battery system, because of the issues of handpropping,so it was easy to put a 12 volt Facit fuel pump in the fuel system plumbing. I've tested this headpressure issue a couple times by running the engineat 2000 rpms without the fuel booster pump. After as few minutes the carbstarves, I flip on the booster pump and the problem goes away. So, part ofthe checklist for takeoff, landing and low fuel tanks is put the booster pumpon.Gordon Bowen -Homer AlaskaCozy IV N64CYOsprey II N64SYPietenpol N-1033B" But such is the constitution of my mind I cannot avoid forming an opinion", JohnAdams.

The fuel line from the carb MUST be a continous slope down to the gascolator, then up to the tank. No place for airto accumulate. Fuel starvation is the most common reason of engine failures. Design your fuel system very carefully, and double check fuel delivery rate, with the airframe jacked up in the highest angle of attack. In this attitude,it should deliver at least 150% of the maximum fuel consumption of the engine. 200% would be even better.Chuck G.________________________________________________________________________________

One time I had a hose swell inward due to age/deterioration. The passagewaywas almost completely restricted. It was not evident on the outside of thehose. But was a dangerous situation.I had a similar experience, but it wasn't due to age / deterioration. I madeup an AeroQuip hose, with the replaceable ends, and it scrunched up therubber inside of the hose. I caught the problem while doing the fuel flow test,before I even started the engine. I tried several more times to install thatend of the hose - No Joy. Possibly didn't use the proper Cuss Words !! I=20nowuse auto fuel line, and barbed end fittings, with double mini clamps. Ichange this auto fuel hose at each annual 'Condition Inspection', as regularmaintenance. I recently bought another Aeroquip hose (as well as the 'InstallationTool'), and will attempt installing the ends again. I much prefer usingAeroQuip hose (with 37=BA Flair), than the auto fuel hose.Chuck G.________________________________________________________________________________Date: Thu, 07 Apr 2005 00:57:00 -0700

Subject: Pietenpol-List: Burl Wood Instrument Panel (Help)I just received my premium elm burl veneer from Constantine's Wood Center in Fort Lauderdale, Florida... Wow! This is a very pretty wood and thanks to those on the list who steered me to their website. (Good folks to do business with...)The veneer is very delicate and I hope to use it over a spruce plywood that will go into my instrument panels. I almost hate to put instruments in the panel because the burl is so nice looking.Can any of you experienced in working with burl provide me some tips before approaching the task of adhering the burl to my spruce plywood? This looks moredelicate than I had anticipated. I'd also like advise on what type of gloss-coat to put over burl.I'll be ordering a gallon of Press Bond Glue from Constantine's later today (wish it came in smaller quantities)...Thanks in advance.Sterling Brooks5TA6San Antonio Sectional________________________________________________________________________________Subject: RE: Pietenpol-List: Google gets more amazing . . .Date: Thu, 7 Apr 2005 07:23:39 -0700I suspect some images are older than others. When I looked at Cox Fieldin Apex, NC, where I keep my Pietenpol, I saw my old Cessna 140 tieddown (easily recognizable because it was solid orange, with blue andwhite trim - no other orange airplanes around). I sold that plane inApril of 2002 to a fellow from out of state, so this image is at leastthat old.Jack Phillips, PESr. Manager, Disposables Product DevelopmentClinical Technologies and ServicesCardinal HealthCreedmoor, NC(919) 528-5212-----Original Message-----
