Got a 2001 50 hp merc that runs rough at idle and when running it at low speeds. It stalls, pops, farts and whatever when your not running wide open. Is carbs the main issue with these engines? I put new plugs in it yesterday and never helped a thing. Plugs were very black. I remember when it was even brand new that would pop and miss a little especially in nuetral when you would try to warm it up. Any ideas? thanks!
