Hey guys, I am new here and have very little experience with outboard engines. I recently bought a 2006 honda 90 that has been sitting for about 3 years. The motor will run with the warm up lever all the way up, but will not idle. My primer bulb goes soft as soon as I crank it over, so it's losing prime. I can prime the bulk with it disconnected from the engine and it stays firm, so I must be losing prime on the engine side. I replaced the anti siphon valve but still losing prime. I cannot see any leaks in my fuel lines or carbs. Where should I start? I know the carbs need cleaning, but would that cause it to lose prime?
