Rough Idle

Wait. Did you say carb cleaner?
And the driving part was also last November?
Well how did it drive during that week? and how much gas was in it when you put the cleaner in there? and how much gas was in it when you parked it?
The point is; the rough running may have nothing to do with the cleaner. Six months is a long time to restart with no issues at all.
For instance, points oxidize. Carbon delaminates.Valves stick.Floates stick. Pilot jets plug up.Distributor caps collect moisture. Mice chew stuff up. Lots of things can happen.
-Now, having said that though,I agree with Snake.
Most carb cleaners are fairly powerful. You may have to go through the entire fuel system. It kinda depends on how much cleaner, and what kind of cleaner, remained in the tank last November.Put a new fuel filter on it too.
