Walbro Carburetor

My Old Kohler k241 Spec # 46764d Serial #9612093 is probably going to need a new carburetor, as I believe the non repairable inlet valve seat is probably shot. The Service Manual lists the Walbro fixed/adjustable as well as a Kohler Carburetor available for this engine. Which one would be better to put on this engine as replacement? The rest of the engine is completely rebuilt and runs great, ( when I feather the fuel with the fuel shut off...or the Carb will pour fuel out the air cleaner.

From the Kohler site, this is the part number of the carb for your engine: A-237772.

I have had luck using a q-tip dipped in rubbing compound fixing bad seats. Put the q-tip in a drill and spin it in the seat to remove pits, burrs, and corrosion from the seat and re-surface it to seal like a new one again.

Walbro Carburetor

those are all great ideas! I have loaded the tips and lapping compound in the truck for a trip to the shop. (you all must be confident that this will work, nobody suggested a replacement for the carb!)

Thanks!

Walbro Carburetor

Well, I hit the inlet seat about 3 times with fine grit lapping compound on the end of a q-tip attached to my electric drill, cleaned it with carb cleaner and flushed it with compressed air. Re assembled the carb and hooked up the fuel line with the carb resting in my hand and the inlet valve on. No leak. Hooked up everything and installed it. No leak yet. Started the engine and ran it. (It never ran this good) I let it sit for awhile after plowing snow and it never leaked. I won't need a carburetor for awhile!

Thanks again!
