Just about done fiddling with a K301 and decided to get the carburetor douched out on the new to me K321 which came out of a 149. While cleaning the carb from the K321 I noticed the upper screw for the air cleaner was cracked. Not a big deal really. Then I remembered I have this carburetor I scavenged off an olde cub years ago. (that's another story)

Here's where the fun begins. Digging that rogue carburetor out of the bottom drawer of my roll-away I notice the choke butterfly has spring loaded reeds. My interest is piqued. (carter casting #C236315, stamped E235058, main needle 235415) Checking the reference manual and cross checking with parts tree and CC Specialties I had decided it is indeed off a 10/12hp engine.

Interesting note... Of the three carburetors I have for 12hp engines no two have the same choke butterfly. (all carter casting #C236315)
1) two small holes
2) one small hole top, one larger hole bottom
3) one small hole bottom, 2 reeds top

Also, the reference manual denotes one of the 12hp carburetors uses a #2 rebuild kit where the others use #1.

Anyone know the difference between the two kits? Needle seats?
