it seems improbable, but it could be that the throttle shaft on the carbs is
worn and letting air in. I know when it happened to me that my car would run
perfectly some days and not at all others. Sometimes when it ran it would also
start running like s!@# and then cure itself. Yours may just get pissy about a
certain throttle position. Best check is to try and wiggle the throttle shaft
AFAIK.
