I hate it when people are right but i have to give it to you, there was no vac at the carbs leading to the distributor advance but there isnt vacuum after a partial opening of throttle, but i figured it out and the timing is very much correct right now but there was a hidden issue i overlooked for the carbs... one of the pump levers is sticking closed so when i blip the gas it lags excessively from the second carb, the second carb pump lever is on point to accelerate but the first carb lever only goes so far before it jams and then it starts missing at higher throttle opening so it was an issue i kept overlooking oof but thanks for the help on the vacuum lesson! I got it after a few times running what you said through my head
