Hey guys, she's an electric start, 25 hp johnson, J25tecdc, 1986
I swapped in a new powerpack, its running now but is having hiccups somewhere. I'm not sure whether its electrical, fuel related, or something else.

I get the ball primed tight, engine starts easy, but idles a little rough sometimes. At random moments of acceleration the motor will bog down, sometimes dieing and sometimes picking back up after a bit. Cuts out at random rpm ranges, mostly mid to full.
Notes to make: Since opening the air valve in the gas tank, the prime bulb does not lose its prime much at all, stays tight running and while sitting. Powerpack swapped out, as well as the one coil that wasn't firing. The carb I bought got completely rebuilt, it was for a prior year model but had the same throat diameter, etc. I removed the orifice plug and installed the plug from my years carb ( clean and brand new, installed correctly with jet screwdriver tool.. 47 to a 49) Put a new fuel pump in last season after a piece of plastic snapped off in cold weather while I was replacing the fuel lines.
Does the fact that my bulb is staying tight elimate a fuel issue? Idk if there was an air leak if the bulb would stay solid or not. I'm not sure what it could be, but any ideas are greatly appreciated.
These problems are the same cold or hot
