This all took me months to do because we were waiting on parts and machining for so long.
So, while that was going on I "rebuilt" the carb. This carb is total hammered dogpoo. I think I should have just ordered one of the Chinese carbs and not tried to save it, but it is still on my engine right now and is working okay. The carb the machine comes with is a Mikuni Solex item that does not seem to be at all available, I found some listings for similar ones, but they all were from sketchy sources and had big shipping charges or absurd lead times.

Not really a 2 BBL, she's got a plug in the one side:

Intake will take a 2BBL carb, this pattern was used by Toyota and Suzuki, so there is stuff out there:

This float/needle/seat setup is unique to the Bobcat. My kit did not have the parts to fix this. I wound up lapping the needle and seat with valve grinding compound and a drill. It never wound up being perfect but it worked. The red gaskets under the seat are the shims to set float/fuel height:

Accelerator pump housing is badly corroded from water contamination/ethanol gas. I was never able to make the accelerator pump work, the machine does run okay despite it but you can not go from idle to "full throttle" quickly or it will stumble:

Difference between the needle valve and seat in this kit. You can't use the one it comes with, they don't work with the float. There was some floats available, and some other kits are rumoured to have the right valve and seat, but I didn't try buying a ton of parts to see because the carb is realistically junk even though I got it to run decent:
