Subject: [FlyRotary] At least I= didn't....

Cause an interplanetary probe to crash or an airliner to= run out of fuel.

You know, one of those stupid mistake caused by in= correct conversions.
My conversion trip-up was converting "front rotor"= from the car to the
airplane (and ignoring the "F" and "R" that I stam= ped into the rotor
housings).

I had fuel.  I had air.  = ;I had spark.  It was just that the spark was
going to the wrong r= otor.  And I used a timing light to verify that I
was getting the = spark.  Except I took the timing from the wrong rotor.  
I eve= n searched this group and verified that I had the EDIS-4 coils
wired co= rrectly.  Connectors 1 and 4 go to the front rotor.  Given that <= BR>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 eng= ine (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 starte= r 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 stal= l for a split
second.  Check your spark plug wiring.

Good n= ews:
- FIRST TAXI !!!  It was only about 3ft, but it is the first t= ime in
this ten year project that I've had something to move under its = own power!!

- The manifold modification is a success.  I had th= e secondary injectors
spraying backwards, away from the runner, under t= he theory that it would
help the fuel vaporize better.  Wrong. &nb= sp;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 sl= owly choke down as it was sucking
some of the puddled fuel out of the m= anifold.

- 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 t= he fuel actually
getting burned AS it is injected and not after it has = pooled a while,
have combined to throw off the current tune.  Fort= unately, 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'.
