I wanted to post a follow-up to my on-going saga of the extra rich #1
rotor.  You can see my post below to see where I was at a week ago.  To
pick up from there, I ordered 10 diodes (p/n per RWS schematic).  They
arrived by UPS yesterday morning, so I raced out to the airport and
installed them.  After re-setting Modes 2 and 4/5 back to the factory
defaults, I attempted an engine start.  Two hits on the primer (program
button) and the engine started right up and idled nicely at 900-1000 rpm.
 (Keep in mind this is a P-port motor; PP motors aren't known for their
low/smooth idle.)  This was a very encouraging sign!  After a little
warm-up, I ran it up to around 4500 rpm with only a slight blip at staging.
 I had to quit due to rain.  I went back out to the airport this morning
and ran her again.  Start-up was picture-perfect.  After warm-up, I ran it
to WOT with only slight tweaking of the mixture knob needed.  Up and down
the rpm range, slight tweaks with Mode 9, but all in all, very smooth.
 I've never had it so good!!!  Now if they would just open the airport I
could go flying.

Thanks to everyone for listening to my whining and grumbing, and for all
your excellent suggestions.

Mark

Hi Tracy,

Well, it looks like your hunch about the diode being bad wasn't very far
from the truth.  Actually, when I started looking,  R2 & R3 both had
diodes, but not R1, the diode was actually missing from R1.  If that wasn't
bad enough, I also discovered that some time in the past, while changing
intake designs, swapping injectors, etc., I ended up with the diodes on the
secondaries instead of the primaries.  So, I just wanted to check to be
sure as to how they are intended to be wired.  Can you please explain so
that I can maybe get it right this time?

Thanks,
Mark
