Before I would go crazy working on the engine I would get a good dist and get the total timing up to at least 42-44 degree's esp if the car comp is below 9.1 On the carb I would check jet sizes most carbs are over jetted not sure in your case but timing and geting it all in by stall speed sure will help.I'm sure the timing will get a pooch to go better try it it cheap and easy to do or change
