Carb issues - engine stalls mid-rpm and above

[Jjacobson01]

I’ve replaced fuel lines, primer bulb, swapped fuel pump, rebuilt carb with kit and tried several times to flush/clean is out -carb cleaner and compressed air. What am I missing? Could there be something plugged I can’t get out? Should I try soaking it in something? 25hp Bigfoot 4-stoke for reference. Appreciate any help

try supplementing the fuel pressure with the primer bulb while running. If stalling goes away...you have a supply problem
