Paul,
I used to get a few drops of fuel out of the throttle
body also. On someone's suggestion in the group, I
installed a switch (safety locking) on the primary
fuel pump. On shut down, I set the engine to about
2000 RPM's and shut off the primary pump/ It runs for
just a few seconds, and then dies. No more fuel leak.
Apparently the fuel dripping out of the throttle body
is due to leakage of the injectors with the fuel rail
still pressurized.

thread the needle through the lowest spot in the
trees.(Pucker factor) I wish I could have taken the
airplane to Mobile Downtown airport with it's 11,000
foot runway, but trying to get it there with the
non-removeable 12 foot canard on it would have been
precarious to say the least. Would have to go
through too much of the city compared to the country
back roads we took to get to this country airport.
The first thing I am going to do is to "un-do" the
leaning adjustment that I made to the MicroTech ECU.
I initially did that because I was getting a few
drops of fuel dripping out ot the throttlebody after
shutdown, and thought perhaps it was too rich, so I
leaned it out. Most likely my biggest mistake. Gotta have extra fuel with that extra air that comes
in when you open the throttlebody.
My climb speed was 110 knots, (when I could get
it) and the oil temps were 160 F. Nevver got above
that on the oil temp. Paul, I need more power,
Conner

Congrats Paul! Welcome to the the club! Glad to hear you made
it up & down ok. But I must agree with Rusty, as I'm
sure your probably already aware and get that power
issue resolved. I can't imagine having to aim for a
gap in the trees when flying off a paved strip
(heck, any strip for that matter). You're probably
correct in that it's a fuel mixture issue. If you
already know that you've programmed it lean, then
this is the logical place to start as it takes fuel
to make power.
Good to hear that your temps dropped on climb
out, hopefully they will still be able to hold their
own when you make more power. What was your climb
speed? What about your oil temps?
Again, congrats and welcome to a very
exclusive club.
