Kohler carburetors

[Jeff_B 10]

Are the 10hp and 12hp Kohler engine carburetors of mid-1970s vintage interchangeable? I need to do a carburetor rebuild, and would rather rebuild one from a parts tractor. In case I mess something up, I could put back the original carburetor and be no worse off than I am now! Also, any recommendations for whom to buy a rebuild kit from? Not necessarily the cheapest, but decent quality. Thanks in advance!

I'm fairly sure 10 and 12 horse would be interchangeable.

Others, correct me if I'm wrong there.

 

I'm not at all a fan of aftermarket carburetors so I would highly recommend that you do rebuild one off of a parts tractor that is an original Kohler carb.

 

Use an original Kohler branded rebuild kit.

You can get them off of the internet from a million different places once you figure out the part number using the search on this site.

 

My general procedure is to soak them for two or three days after I disassemble as far as possible. I don't normally take the main jet screw out of the bottom because they can be just plain downright stubborn and it's not that big a deal from my experiences if it's left in and just cleaned from every angle possible. 

 

After you soak it for whatever time is necessary grab yourself two full cans of brake clean. Spray every galley/hole/orifice in there backwards forwards in out up down left right and sideways. 

 

Reassemble. Hope for the best. Don't get discouraged if you have to repeat it all over again after you just got done.

I also recommend using a genuine Kohler rebuild kit, part number 2575701S.

 

Here is just one source to order one from. http://www.psep.biz/store/kohler_carburetor_parts.htm

I've gotten three or four genuine Kohler off of ebay for around 12 bucks with free shipping....
