As it turned out he had both mags fail soon after heating up and he spent the afternoon keeping the cows away from an undamaged airplane. As it turned out one was likely breaking down soon after takeoff for sometime but would likely leave no warning to the pilot of this type of airplane at the weights it was typically flown and even then it would be tough to spot. The other decided to join it with him flying the airplane. One thing is for sure. It has to be either something with the fuel, ignition or a problem with compression :-) Let us know what you find. Never know when someone else will see the same problem again. ________________________________ Message 3 _____________________________________ Time: 07:44:46 AM PST US From: Michael D Cuy Subject: Pietenpol-List: $7,000 Piet on Barnstormers.com 0.01 SUBJ_DOLLARS Subject starts with dollar amount Just saw this on barnstormers.

I don't have my motormount ready yet but I need to figure a spot on my firewall where most folks are hanging their gascolators for the Continental A engines. I recall that most everybody has them as low on the firewall as they can be placed, and I also recall someone ripping one off during a very hard landing, so maybe they can be installed too low? Does anybody have a picture of their firewall showing their gascolator location they can e-mail to me? I'm building my fuselage tanks (yes tankS) and I need to know where my gascolator will go before I get too far along with my Styrofoam tank molds.

Engine would start and run fine but the fuel 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 until the air bubble worked it's way back up to the tank. No problems after that.

I put an O-235 on N-1033B, while testing with only a couple gal. fuel, the carb acted starved. This engine was designed for planes with fuel tanks in the wings, therefore a couple lbs of headpressure. The tank behind the firewall on the Piete seems to me to be too low to maintain much head pressure while the engine is sucking fuel at 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 engine at 2000 rpms without the fuel booster pump. After as few minutes the carb starves, I flip on the booster pump and the problem goes away. So, part of the checklist for takeoff, landing and low fuel tanks is put the booster pump on.

Just lift the tail as high as possible for a minute or so until the air bubble worked it's way back up to the tank. That's the first thing I thought of. The fuel line from the carb MUST be a continous slope down to the gascolator, then up to the tank. No place for air to 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.
