Dropped floats would definitely cause all of that. If it sat all winter without being started occasionally, and without the right amount of fuel stabilizer in it, then the gas in the line and bowl also could have evaporated leaving a bunch of yellowish crusty crud in the carb which could clog the needle and seat (flooding) as well as the jets and rods (poor idle and performance). Either way, probably needs a rebuild.
If it has brass floats shake them to see if you can hear fuel in them, if not use a pair of pliers to emerse them in water just off of boiling. The hot water will expand any air in the floats and cause bubbles to rise from any pin holes in them, which are usually in the solder between the two halves.

May have dirt on the needle and seat as it sounds like its flooding. May also have a heavy float but how far did you drive it and how hot was the eng ? Ron

take off the tree/rods etc then the top to get at the innards & see if there's a bunch of crud (as said rebuild if it is that bad or just blast out the bowl with a can of brake kleen) as (if) needed. Wouldn't hurt to replace the needle/seat assys while you are in there with some good quality pieces. If TQ needles/seats are seperate (iirc they are) then twirl the tapered neoprene tip on the seats in between your thumb/forefinger to smooth them (that's my OCD talkin) and be sure to blast the seats. As said check your floates & a good procedure was posted above. Short version: replace the filter with a Wix/twirl the needles/inspect the bowl/check/reset the floates.

I never gave that any thought (till now) as I treat all chemicals as toxic (especially the ones that flash off/vaporize quickly) but I went into the kitchen & looked at the can of brake kleen and it is non chlorinated so I think I'm good (& no I don't use it inside!). Just me I dont see a problem with blowing out the carb bowl with it even if it was chlorinated tho my favorite brand (cheap) is no chloride (done it many times) in a well ventilated area tho (car near the shop door/door open)

Use carb cleaner, not brake cleaner. Do you have brakes in your carb??? I wouldn't recommend burning any type of brake cleaner. There is a difference between carb cleaner and brake cleaner...they make both for a reason. And definitely don't run the car indoors. Any of these things can be hazardous if used improperly.
And guess where a lot of that gas has gone...down into the intake. So when you first fire it up, it will probably be extremely rich (high CO).

Car near the shop door is not outside, now that is living like it is your last 24 hours! LOL.
Carbon monoxide is colorless and odorless. Stop fooling yourself, get the car outside. (1) excellent humor brother (for real) (2) I did not mean running the car next to the door I meant having it next to the open door when spraying chemicals (such as my non chlorinated Brake kleen) into a carb bowl to blast/clean it out
