- Webra 145 AAR

[Woodward James R Civ 416 FLTS/TPS]

Interesting... My observation after running the AAR is that it is almost
"clinically-clean", there was almost no residue all the way back to the
stinger exhaust.  Your probably just too rich.  I have not made any
adjustment to the Webra pumps.  I did all the pump adjuting I could wish for
when using the ST2300/perry pump combos.

You may need to back off the pump pressure a bit. I have a Bully 1.45
(basically same as Webra) that ran terrible and blew a ton of fuel out until
I unscrewed the pump screw 3/4 turn. This made a huge difference it the way
mine ran!  I could probably still go out another 1/4 turn.

Of course this may also depend on the position of your tank, orientation of
motor, etc.

Good luck,
Keith
