Had this carb on since I bought the Landy 2 years ago. Always had an inline filter and been working fine. Out of nowhere it wouldn't idle. Stipped it down and found no obvious blockages. Still wouldn't idle unless idle speed was significantly increased. Spent 3 days researching and overthinking the issue. Should I refurb it ? Decided life was too short to spend any more time on it. Bit the bullet and bought a new one which idles fine ! This carb would suit someone who knows more about carbs than I do. Happy to answer questions ????
