B434 Carb trouble

[Whatswrong]

I have looked on various sites trying to find a new carb for this tractor without any luck, has anyone experience with flipping the manifold over and put an up draft on anything similar .I can see the exaust would need some modification also .My main issue is if the switch would actually make the tractor run or would I be wasting my time ,reworking "stuff" is no concern.

I'd leave it alone and if it needed fixing work with what you have. It's not that you can't do it, it's the value of it for the time.
