Hey Im not knocking it.
There where air bubbles in the line from the regulator to the needle.
Solve that and I'm sure it's fine. Just couldn't solve it!

Did 4 flights with the FX/Perry today.
Engine ran well through out, no dead sticks.

The situation now is as follows. Top end good, bottom end good, Mid range rich.
Adjusted the LS NV to the point that, well, half a turn more stops the engine.
So what's the next step, unscrew the pump one turn? I'm tempted.
I'm in your hands.

Engine feedback.
OK, So it's not a YS.
But jez' it's simple.
