Carb flooding on my 128 w/ a K301

That's not the correct carburetor. If it was rusted off, how did you tune it?

I bought a new oem kohler needle and seat as well as a float. It still floods.

Are you sure it is "flooding"? I have taken carbs apart and found the "baffle gasket" was not positioned correctly when the bowl was tightened down, it would then be distorted and leak.
As far as the "China clone" carbs, I have used three of them and all worked perfectly right out of the box. Almost cheaper than a carb kit although I don't know how long they will last.

That's not how you adjust the governor. You should try to get that threaded rod back to the way it was and follow the instructions in the manual.

I have also used two of the cheapo china carbs.
First one, the float developed a leak and filled with gas.
Upon comparison to a Kohler carb float, it was obvious that the china carb is soldered by hand and appeared to leak where the solder was not visible as in none in that spot.
The china carbs do not appear to tolerate ethanol gas as well as a Kohler carb.

As mentioned, pushing a rubber hose onto any fitting can sometimes skin some rubber off the inside. It might hang there for years before it comes off and goes downstream.

The rubber cone on the float needle might be petrified after 40 years.

Never got far enough to tune it because gas was running out of the hole just under the choke butterfly.

Your cheapo carb is one step above mine with a plastic float...

I tried a new oem kohler needle and seat on the old carb already

Thanks. I put the rod back like it was. I left the backing nut where it was so that I could put it back in case lengthening the rod didn't work. (Not my first rodeo!)

Thanks for the advice, everyone. Saturday AM. I cleaned the gas tank again and dis assembled the china carb to be sure there wasn't anything under the needle. I didn't see anything, but when I put it back together and reinstalled it, the tractor ran good. I changed the oil to be sure there was no gas in it and tilled up my garden (12'x20' or so) with no issues.

As far as flooding, the china clones do have positive reviews from some users here.
I'd be more suspective of a small piece of rubber fuel hose or a hair or two under the needle seat, it happens quite often.
Flooding is caused by the needle not seating, for various reasons.
You need to investigate why.
As far as your old carb I'm not familar with your model, but I don't think the bowl nut jet adjustment was origional but not sure.
I'm sure others more familar will reply.
Did you set the float level properly, according to the manual?

I will post a photo of the carb some time if I can remember. As mentioned above, I set the float level per the included kohler instructions.
