My JD X127 engine, B & S V-Twin 656cc, model 40N8770072B5 runs but is continuously hunting After removing the air filter and spraying the intake with carb spray the engine runs smoothly for a few seconds and then starts hunting again. Same happens when a little choke is applied. If I rev up the engine holding the governor lever it runs fine but when released it is hunting again.
Checked and cleaned plugs; replaced the fuel filter and checked fuel pump flow. I'm a bit hesitant to tackle the carb - the machine is less than 2 years old. But now at a loss as to the next steps to solve this.
All suggestions gratefully received!
