Hesitating throttle and popping noise

Hi
  Just a thought.. When was the last time you had the valves adjusted ? I think its every 9k..Also what type of gas do you run? I always run the same  Chevron 91 octane ...Good Luck,,

You can, and should, adjust the mixture screws while she's running, don't have to pull the carbs for that...

Thanks for the tip, Rich.
Are the mixture screws hidden underneath the golden plugs on the engine side?
Do I drill them out to access the screws?

They possibly are , but be carefull drilling out the brass plug, the mix screws are just below them,,,most places got the carbs with the rubber covers over the mix screws
