"I have a 40hp 2 stroke 4 cyli
"I have a 40hp 2 stroke 4 cylinder Mariner Outboard. It sat unused all last year. Now I believe it is running on just one carb. It will start and run on high idle, but will not stay alive on low idle. The top carb reacts to carb cleaner or choking by hand...it starts to die. But the motor reacts not at all to the lower carb being choked or sprayed with carb cleaner, although there is steady suction when I choke it by hand. I've been told I need to take the carbs apart and clean them. Sound right ? Can I do it without a manual ? Motor ran fine two seasons ago"
