360 stalls when put into gear

Hey guys just joined this forum. I’m 18 and I just bought a 1984 d250 with the 360. As most of you probably know it had the dreaded tq carburetor. I rebuilt it once and got a new resin piece for it. I think it took the carb off about 6-7 times for various problems. Fuel leaks float adjustment etc. They have all been fixed except since my last fuel leak out of the carb that I fixed it has another problem. It doesn’t start when warm and two when I place into gear and then start to accelerate it stalls. It’s not the accelerator pump as I saw the fuel being shot into the primary’s when I pumped it. Any ideas any of you guys have would be greatly appreciated
