I’m trying to fix my buddies Trot Built mower that is about 2-3 years old. As the title says runs great then starts stumbling and quits . First thought was the gas cap vent , nope . Then I filled the tank pulled the line at the carb and let it all drain. No issues with the shut off valve and it flowed free straight to the bottom cap on or off no change. I put it back on the carb and tried it again same thing shutting off. Both times I noted the auto choke was working properly before and after.
On to the next Honda possibility the spark plug. I swapped it BR5 es with the BR6 from my pressure washer, did the same thing.
Ok I’m stumped. I did yank the bowl which has much of the plating munched off it by ethanol.
That’s where I am right now, any brilliant ideas
