That's a good thing to do. I'm assuming you have the single Stromberg carb?
Anybody think that too high a float level (or a bad choke/enrichment) could
cause this? Gas floods the intake which causes sputtering because its not
properly atomized.
Seems as if it would be easy to remove the air cleaner and peek past the
air piston to see what's going on at idle.
Or, pull a sparkplug. It should be light brown, not white (lean) or sooty
(rich). Inspect them 1) after the car has been sputtering and 2) after the
car has just been running well. While you have the plugs out, gap them to
.025" (stock) or to .035" for an aftermarket electronic ignition.
Good Luck,
