My feeling is that there is a problem, maybe bad spark plugs or something to do with the valves. Anyone have any suggestions, or have had this problem too? Thanks!!!

What kind and how many carbs? Recent maintenance, if any? Pulled any plugs for a look-see?

What is your idle RPM?
Check the plugs.
When was the last time you adjusted the valve lash?
