Check you have the cut-off valves powered (remove and repace the connection
with ignition on and they should click).  Also check the balance pipes are
connected at all their joints.  This can cause lumpy running too.
Otherwise it could simply be dirt in the carb idle jet(s).  One carb not
working properly gives very lumpy running except at high rpm when the
balance pipes make up for it.
What about choke flaps - are they powered and backing off properly (look in
with air cleaner removed)?
