Hey everyone, need a little help here. I have a 91-140HP Looper that is on my Flat's boat. Great little engine ( I say little because I have two 225's on my Scarab). Anyway, When I was out recently, the engine has started hoping at higher rpm's.:/ It does it in gear, or in neutral. Idle sounds good, start adding throttle and it's all good. You get to a certain point is just starts missing on at least one cylinder. It sounds like only half the motor is firing.:'( If anyone has any suggestions, I'd love to hear them. I can work on the inboard stuff, but the outboards are new to me... Thanks, Capt. Jim.8)
