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'.
