"Well, it's some better." - I say... The ceiling is dropping and ten
miles out we are forced down to 800 feet to stay out of the clag... We
go back and land and taxi in... Steve is out on the ramp, still all
smiles... I pull the mixture to cut off - and the engine continues to
run - and run, and run, shaking and wallowing like a wet dog - Steve
is not smiling... I goose the throttle to break the vacuum that is
pulling fuel through the carb, and it winds down... "Well, that's not
better." - I say... Back to square one!

I would have thought that this problem would have manifested itself when the
engine was shutdown after the test run and leak check post carby fittment.
