Hi Blake,
This may not be the case with your car but I've run into it more than once.
You may have a stuck float needle in one of the carbs. In this case the
engine gets quite enough fuel to idle happily on only one carb but as soon
as you open the throttle the mixture is WAY too lean and she'll burp and
fart and produce almost no power. If this IS the case the diagnosis and
short term fix is to give each float a solid whap with a non-marring
micro-adjuster or BFH. The occasional miss on #2 leads me away from this
diagnosis but you never know; it's quick, easy and worth giving a shot.
Good luck.
