I haven't tried it yet but there has been a lot of success with using a $20 carb on e-bay (china) I believe it is for a Kohler 582 twin? I bought one but have not tried it. If you go on facebook you can join the 616,620 and 720 sight, I believe it has some discussion on it.

Ok, I found that page now and the carb they recommend. Does your original carb have a flange adapter bolted to it for the rubber boot to the filter housing?

Yes it has the air cleaner hose. Like I said I have not tried it yet but from what I have read the only alteration is to open the air holes. Did you find the article on the FB website?

I believe this is the carb everyone is using on the conversion. Although it can be found much cheaper on Ebay.

https://isavetractors.com/carburetor-for-kohler-k482-k532-engines-18-and-20-hp/

Two of the holes on the face have to be opened up to meet the inlet, using a dremel or a file. If you compare it to your stock carb, you'll see which holes we're speaking of.

You are correct, I bought mine on E-bay for $25 with shipping.

I have read that there are definite quality differences in the Ebay carbs and the Isavetractors version of the carb. I have no experience with this myself just yet. I've also read just how happy the owners are with their tractors after swapping to these carbs.
