carb rebuild

cub108 · #1 04-29-2011, 09:51 PM

Does any one have the Kohler numbers for the carb rebuild kit for the 10 horse motor with the Kohler carb. I am almost certain it is the Kohler carb by looking at the pics i found. It does not have a name on it and it has three adjusting screws.
Is there a master rebuild kit? all gaskets, float, needle seat, idle and fuel adjusting screws, throttle shaft bushing, or do i have to buy things separate.

If so, can i have the part numbers of each or please send me just a link with the info.
thank you

Your carb should be a #26, look down the throat behind choke butterfly, should have a raise 26 cast into the top of the carb between the choke and throttle plates. It uses a KH-25-757-01 kit...here is a link to look up the part numbers from parts tree, you will se the carb rebuild kit under item number 26, ironically:

Member Mattg has his own cub site, go there and he has a very nice how to rebuild your carb!

You need to buy the three parts separately, the float is part number (item 21 on parts tree diagram) KH-25-757-03S and see the pic for part number on the throttle shaft bushing!

The kit comes with a new needle and seat, the bowl gasket, the bowl baffle gasket, and the gasket that goes on the nut that holds the bowl on. Your old springs and high and low needles should be re-useable after some cleaning. If you need those items, they have to be bought separately. The site sponsors have are a good place to order these parts, or go buy you local cub dealer, he most likely has them in stock, or can order them for you saving on the shipping. I ordered my parts from Chis Westfall, Cub Classics, at the top of the page....however, he has run into a snag on the float kits, I am still waiting to get mine, they are on back order!

Here is the link to Mattg's how to rebuild your carb:

Here is what my carb looked like prior to rebuild:

Here is what it looked like afterwards:

I was bored (waiting on parts and what not) so I buffed the case of the carb and the brass parts with a stainless steel brush in my dremel tool, then I wet sanded the bowl with 400, then 100 grit wet/ dry sandpaper and buffed it out to a mirror finish (mother's mag wheel/ aluminum polish)....it looks better in person!

I have a Walbro carburetor with a 52 cast into it. This came with a K301 I bought a while back as a non running parts / rebuilder engine. What would this "52" carb be from? Could it be used on a Cub 109?
