I guess I was hoping for smarter people here. Whenever I speak to
the fuel shops (or any A&Ps) all I get is "it was too rich, it needed
to be dialed down". My concern is still "why was it running on day 1
and didn't run day 2". I don't think the thing can "unadjust itself" in
one day. However, I'm not sure if changing out the spring is just a
'readjustment' or a fix for a problem. Sadly, none of the fuel shops I
spoke to even know how to answer that. I guess they're just in the mode
of correcting what they see wrong, not necessarily finding a root
cause. In my line of work we spend weeks in classes learning how to do
RCA (finding actual root causes of things, not just fixing the signs of
the problem). When I mention root cause I get blank looks from the fuel
techs or A&P. The best I get back is "install it and try it". However,
that means I need to put a certain number of hours on it before I feel
good about flying the family and the Boy Scouts. Also, each R&R is
costing me about 10 hours of A&P time.

Understood. Seriously.

If I'm not careful, my personal "ouiji board" will steer this towards
a rant, been enuff/too much of that here lately.

You want to correspond further (possibly gaining more info, but also
risking a rant) drop me an e-mail.
