help
I have a 80 wideglide the bike starts and idles just fine. When u give it throttle it cuts out and dies if let off it will cat itself and stay running. I have changed carbs running a s&s superb checked jet sizes. I have replaced timming weights plate and points and condenser. Adjusted push rods for valves. Performed a leak down test 18% on both cylinders. Did compression test front 145 and rear 120. Performed smoke test through carb no leaks present. I do have some blow by on the timmig plug. It puts out a good mist. Any ideas thanks

You know the S&S Super B does not have an accelerator pump; hence, the throttle needs to be rolled on more slowly when coming off idle. You are probably not twisting it too fast but I gotta mention that.
I'm thinking the carb's transfer ports are plugged or restricted.
If that is the case, those ports need cleaning out. Using a spray can of carb/choke cleaner, flush them out. If you use a piece of fine wire to help get crud out of them, be careful to not distort the holes or break off the wire in them.
