Lawn Tractor Carb

Kohler engine -Walbro - 4205303 carb - "cleaned" LMK with carb spray blew out with air , will run for a few seconds if I pour fuel into carb throat, then quits. Solenoid is working, even removed and used plug in lieu of solenoid. fuel inlet needle has silver tip, orange looks good. could it need replacement?

Hello dp3466,

Sounds like something is still clogged, Look at THIS page and make sure carb cleaner passes through all the jets-ports and passages. Do NOT and I repeat do Not remove #10 welch plug nor the throttle and choke shafts, If you see cleaner come out other ports while spraying into one the holes behind the welch plug are likely clear......


Good Luck

Think all passages were clean. Got to be a stubborn port I haven't cleaned.
Am thinking the plug you mentioned has two tiny and I mean tiny holes visible in the wall. Now got to back and figure if it is one of those as rest seem to be clear. The site was helpful.

31YTech - Well I have added a supermarket twist tie to my tools. From the float side, the center shaft has a smaller tube in an offset position. Although it appeared to pass cleaner, it apparently did not. By carefully prodding the twist tie wire into the 'tube' and using a widened shaft on the cleaner can over the 'tube', blew out the obstruction. Mower ran and the final test will be tomorrows mowing.
You were correct - Many many thanks.
