Replace the starter solenoid. The buzzing noise is most likely the coil in the solenoid.

Remove the carb soak in carb cleaner, **** out small bleed holes with a wire from a wire brush etc. One of the passageways is still clogged, or the float is sticking.

I would guess stale gasoline or fuel. Try fresh fuel in the tank. If this doesn't clear the problem, you could need to have your carburetor or fuel injection system cleaned. I'm not even sure if they put fuel injection on Sportsters since I don't work on fuel injected bikes. I mostly work on the older bikes like Panheads, Shovelheads, Evos. Not too many Sportsters but have worked on a lot of Ironhead Sportsters. Try the fuel first. It's a cheap fix. Hope it works for you. Good luck with the knee replacement. My wife had one knee replaced and it works great.

I would check both spark plugs then check the timing and if not fixed check the coil to see if it is bad.
