"Hey guy, hope someone can help me. I have a 1985 mercury outboard that will run smooth for 4 seconds then violently jerk, run smoth for another 4 seconds then jerk and on and on. this happens during idle and low trolling speeds. Slam down the throttle and she takes off up to 55mph without a miss. Cleaned and set up carbs, replaced plugs and rectifier. Any thoughts would be helpful. thanks"
