11HP B&S flooding
I have looked through numerous messages with a similar problem, but no solutions for mine yet. The engine starts fine, but after 20-30 seconds, the carb floods and the engine dies. So far I have: replaced fuel lines and filter, cleaned and re-built original carb. I then bought a "new" refurbished carb because the last time I was reassembling the old carb I broke a piece of the housing. Problem STILL exists. I was told that it may possibly be a valve issue. I have verified that the valves are not stuck, but it is possible that they are not seating properly. Engine is about 15 years old. Any ideas/advice?
