Should you think about an effort to measure fuel pressure at speed? A tee
in the fuel line and a simple gauge to the cockpit might shed some light on
whether it is fuel supply related or ignition related (by elimination). Cut
the problem in half....

Subject: Re: [Healeys] High speed miss - CARBS?
I still have a misfire at high speeds and at low speeds when I accelerate.
The timing seems to be set correctly and the fuel tank, pump, lines, filter,
needle seats and float chambers are clean. The plugs and points are gapped
correctly.
The carbs were rebuilt but I don't believe the piston/suction chambers are
to factory specifications. The carbs are original and I am wondering if that
is why I am getting the misfire (it is not a back fire through the exhaust).
Has anyone had similar symptoms that were cured only by replacing the
carburetors with new ones?
TIA
