[Healeys] problem keeping Healey running

[rwil at sbcglobal.net (Roland Wilhelmy)]

An air leak on intake side?  Some gap that widens with heat and time?

::Woke BT7 up from winter sleep about two weeks ago, started fine, took out
for a spin, about 45 minutes into drive began to run poorly, then stopped in
heavy traffic, got it started, went home without dropping to idle, running
very poor. Next morning repeated the same, same behaviour. Have checked
ignition (Pertronix), plugs and coil fine, a little sediment in carb bowls,
what could it be that develops after some time under power, welcome advice.
