And then it happens again.
Today I put on the rudder, since it is tied into the nosegear steering, and the new muffler I built. This is the first time that I've run with the cowl on for any significant amount of time. It was taking a while to warm up to 160, even though it was around 80 degrees outside.
Finally, I shut down and was motified to see smoke rising from the engine compartment. Jumped out and grabbed the hose. No fire, but the exhaust had burned the cowling where it passes close.
Maybe I can get the newest repairman to help me out 8*)
The muffler works really well, BTW.

Cause an interplanetary probe to crash or an airliner to run out of fuel. You know, one of those stupid mistake caused by incorrect conversions. My conversion trip-up was converting "front rotor" from the car to the airplane (and ignoring the "F" and "R" that I stamped into the rotor housings). I had fuel. I had air. I had spark. It was just that the spark was going to the wrong rotor. And I used a timing light to verify that I was getting the spark. Except I took the timing from the wrong rotor. I even searched this group and verified that I had the EDIS-4 coils wired correctly. Connectors 1 and 4 go to the front rotor. Given that the front rotor is the one in the front on the airplane, not the car. Doh!! Once I switched the plug wires around and cleared the engine (turned it a bit with the fuel pumps and injectors off), the engine kicked off in two blades. Someone has GOT to develop a cure for stupid, or I'm doomed. Word to the wise. You've verified fuel, air, and spark, and compression. The engine's spinning with the starter at around 250rpm, but it just won't kick off. Every few turns, though, it is like something blocks the engine from turning and it stall for a split second. Check your spark plug wiring. Good news: - FIRST TAXI !!! It was only about 3ft, but it is the first time in this ten year project that I've had something to move under its own power!! - The manifold modification is a success. I had the secondary injectors spraying backwards, away from the runner, under the theory that it would help the fuel vaporize better. Wrong. It just puddled in the manifold. A little more fiberglass work, and both sets are spraying with the airflow now. I cut power to the fuel pump and the engine immediately cuts out. It used to slowly choke down as it was sucking some of the puddled fuel out of the manifold. - I don't seem to have damaged anything with the backwards plug wires. - I've got to rework my tune. Yes, this is a good thing. The aggressive prop is loading the engine, combined with the fuel actually getting burned AS it is injected and not after it has pooled a while, have combined to throw off the current tune. Fortunately, this isn't very hard with a running engine. -FIRST TAXI !! I'm juiced. You guys that are flying better watch your six. I'm a comin'. -- Homepage: http://www.flyrotary.com/ Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
