My new to me WD carb was leaking at the load jet so I removed the carb,
when I took it apart it has no venturi.
Tractor ,runs OK, but I think it would need the venturi for best performance

I'd definitely put one back in there, you can order an oversized one. That won't reallyhelp unless you do some other work to the carb but it's a good start.

do you know what the standard size jet that came in the 464?
I see on McDonalds carb site you can only only order about 3 sizes.

It cannot even run without a venturi.

Part number 46-A 248 is the one inch venturi which will fit a TSX464 and is larger than the original one that came in a TSX464.

Tractor did run, pretty much as normal. it did stumble at higher RPM's though

I put in the venturi from my 17 and it does run better at all RPM's

You might even consider sending the whole carb to McDonald's carb, he will ask you what cubic inches and what rpms your running and build a carb to your tractor. He flow tests them and the whole 9 yards, I've been very impressed with the carb he built me. I would highly recommend him.

My 1" venturi came in as well as a new load jet.
The new load load has 1 hole on the side for fuel intake. The old one has a hole through both sides. I assume someone drilled this out for greater fuel passage?

I left the old one there and with the new venturi, the engine runs much cleaner.

I actually pulled it in 3500 class and it did OK until it bogged down at the end. I was also getting a lot of black smoke from too much fuel.
Came home and decided to check the carb and found no venturi. I was surprised also
