I'd just go through it. It's stupidly simple, and 99% of the time, the float needle valve is the only thing that needs replaced. Unless the float bowl has a gasket that rips.
I can go through a Honda carb from start to finish in less than 30 minutes easily.
I use brake clean, being careful to not spray it on o-rings or gaskets. I clean it with an old toothbrush with the tip ground thinner. I pull bristles from a brass brush to clean the tiny air and fuel ports.
If you like to clean the outside to look like new, the Harbor Freight "suction style" soda blaster works like a charm for that.
As for the carb being for a bigger engine, if you can get the jets at a local cycle shop, just drop the size of the main jet one size and that'll likely take care of it. Or look up the jet sizes for the 90 and switch to those. If your exhaust is more free flowing than original, then the 110 carb will probably be fine as-is.
