When I wrenched for far too many years we would get cars/trucks in with QJ carbs that would have that issue. What I found a lot was the lead plugs on the bottom of the carb for the main jet passages leaked gas and then flooded the
engine. Which caused a hard start to the point you have to hold your foot to the floor to clean it out then it would start. I fixed them by takin the carb off cleaning the spots and then JB Weld over the plugs. Not sure of this is your issue but it sounded fimilar so thought I would throw that out there.
