Default 1985 FLH Coughing

I have a 1985 FLH Tour Classic with a Evo that has been running amazing until yesterday. The motor is still running, but at low speeds when I give it gas it hesitates then coughs. I look at the intake bolts tightened them, and cleaned the air filter, and put in new plugs . I took some seafoam adding the proper amount in the tank drove 30 miles , and its still is coughing. Any ideas?

How long the has it been since the manifold intake gaskets have been changed?

Other possibility is that the low speed jet could be partially fouled.

as CV carbs are plentiful and float with the air filter for around 150 bucks its a great investment 1/3 the cost of an S&S and they work great
