K so I've been on here for a while, but still rather new to boats with something more than electric motors. I've had my boat out a couple dozen times this year with no real probs to talk about. The other day I took my dad n step mom wiper fishin. To begin the day it was a pain to even start. Get it started and warm it up while dad parks my truck. He gets in and off we go. Sounded a lil diff than norm but still good power compared to norm. I idle down to get ready to start trollin and its running rough and wanting to die unless i give it a lil bit on the throttle. Plugs are rahter new. Does this most of the day at low rpms rough idle in gear and out. I get home check plugs and the port side looks good the starboard side looks wet n a lil more deposits. What could cause this n how do i tell if its a cross flow or looper. Thanks J130TLEOA G 03823097
