Cub XT1 LT46 Mfg 08/22/2018 Model KT725-3078 After running for a short time (5-10 minutes) engine bogs down and dies. Doesn't matter if it is under load or not. I have found I can get it to re-start by spraying some carb cleaner followed by starting fluid directly into the carb but it dies again a short time later. I understand these carbs are not adjustable. Considering rolling the dice on an ebay replacement carb. Engine has 218 hours on it. Oil, plugs, filters changed regularly. Most recently last week. Anyone have a similar experience? Thanks.
