I have 60 Yamaha 4 stroke that rough idles and eventually dies out. The thing is when I put it in gear and run it at low and/or RPMs it runs perfectly. Any advice on what the problem could be, or a checklist of the potential things to check will be greatly appreciated.
 
Start at the bottom of fuel tank pickup tube,might be a clogged screen, Check all clamps and hoses for security, IF you have a fuel/water separator, Dump contents into a clear container,sit overnite,look for contaniments at bottom. Is the primer bulb pumping up firmly? Does pumping primer bulb while running help, need asst. This would indicate a fuel delivery issue,clogged filters,weak fuel pump. Is fuel tank clean? Is fuel old or new? New fuel mixed with last years?
