I bet you could swap that carb out for one off a Quantum or Intek. It would take some work, but still doable as long as the bolt patterns are the same.
You probably could. Turns out it's nearly identical to an older Quantum carburetor. Only differences I can tell are the vent tube, the mounting flange being recessed towards t eh center on the Quantum vs flat on this engine, and that deeper bowl with that washer and bowl nut adapter. You could probably use a regular bowl and bowl nut and it might work. Bowl gaskets are the same, which is good since I needed one (even though Toro lists it as it's own number), as is t he throttle valve shaft, which I used from the Quantum because there was play in the bracket the spring connects to.
Nice. I've always wondered what that engine was (seems like a Briggs and Stratton copy of the Suzuki 4 cycle?).
The Suzuki 4 cycle had the muffler on the left side of the engine, when viewed from the front. The valve cover is also different too.
You got lucky as parts are stupid expensive for the Mikuni carb.

I thought it was a Suzuki as well when I first looked at it. I think that's more to do with the shape of the shroud. It's a bigger engine, definitely not a clone. Apparently it's called Europa. I really wanted a Suzuki engine for parts for the Commercial Toro I also just got which has a Suzuki engine that runs great, but burns oil. That being said, I like this engine as well.
This is by far the worst carburetor I've ever tried to salvage. It reeked of old fuel, there was varnish everywhere, the valves were seized, and it was over just in bad way. However, I don't have another one, and as it turns out it, amazingly, didn't have much corrosion on it. So two cans of carb cleaner and a lot of wire brushing later, here we are:
And what do you know, after a little shot of carb spray it fired right up! Runs really smooth and quietly. Reminds me of an OHV Honda engine. I like it! Everything seems to work properly. Didn't mow much grass, since it needs an air filter and I didn't want to suck in dirt, yeah, but I'm pleased. Will idle really slowly which is neat, and started back up after shutdown. Assuming it cold starts on it's own this has been a surprising success. Now it just needs a new deck, or a patch...
