Pull the plugs. Could be one cylinder. You want a nice mocha color on the plugs. Also check to see the heat index of your plugs themselves. I just went through this issue on my carbs. Takes 10 minutes to re-gap some plugs. Also a little spray bottle with water, set it to mist and spray around the carb and intake to check for a leak.
All this is assuming your timing is correct.
