2005 Mercury 115 carb 2+2. 4cyl. Problematic engine. Intermittent rough idle.... seems weird but it seems to idle rough once it's trimmed down all the way...then it clears up on its own after 20sec. Also, I can't stand the 2+2 transition. Is there a way to make this engine a 4cyl all of the time;and is there a kit to synchronize all four carbs in unison. Tips and mods would be greatly appreciated.
