Al,
You may have answered
this already, but have you checked the injector spray patterns? It is
possible that they "click" ok while the fuel orifices are plugged with some
gunk. I took mine and safety wired them to the injector manifold, hooked
up a fuel supply, hit them with 12v and observed the spray patterns.
Probably a waste of time, but it would tell you that you're getting a good mix
of fuel into each chamber.
Mark;
No I
haven’t tested them myself, but sent them off the RC Engineering who cleaned,
flow tested and checked the pattern. There has just been a few hours on
the dyno and on the plane, but that doesn’t mean there couldn’t be something
in there, although there is a 20 micron filter in the line. First I need
to eliminate any electronic issues. I’m not sure the pattern is of that
much concern on the primary; there is that little plastic deflector below the
injector. I don’t know if the fuel actually sprays on that, or if it
just causes some turbulence in the runner right there for better
mixing.
BTW, Initially I had
incorrectly wired my injector relay. It took me a while to figure out
what I had done wrong and correct it. I got it wired correctly now... I
think.
So did
I, but caught that in the first runs on the dyno.
