Need help finding a Carburetor

So it’s a NIKKI carburetor.
Still having trouble finding a replacement.

Said I would try to help if you could supply me with the Wheel Horse model and serial numbers!!?? Offer still stands, if you take the time to get them.

A carburettor is a carburettor is a carburettor.
All that is important for you is the mounting centres of the bolts that hold it on.
After that, any carb will do the job but one from an engine of the same capacity will be easier to set up.
After all hot rodders & street car owners do it all the time.
Perhaps there was a car that came standard with a 4 barrel down draft Holley carb with air rams, but I can not think of one.
After finding the mounting centres & capacity, the next step is to look at the controls.
It will be easier if the replacement has the butterflys in the same position ( Top or side ) as the original.
Then it is just a case of bending some wire to hook it up

That one pic, with the plastic filter, shows what used to be an on/ off lever apparently snapped off.

Not a biggon, turn it on, if it's working correctly it won't leak.

IMO, I'd open it up, apparently one bolt on the bottom.

Could of had it open faster than typing this post...

See what's going on inside..
