Hello First off Motor was all rebuilt last year new piston rings carbs redone lower unit seals etc New 24 gallon fuel tank mounted on a BW montauk. I enjoyed a trouble free year last year work was completed by a very good local shop. Only used the boat twice this year in the water did not start for two weeks. Started yesterday ran fine stayed in slip and motor ran rough like on two cylinders?? New plugs were installed this year cleaned off drained down carbs thought I may have had some sediment. Ran fine on all 3 cylinders then at idle ran rough an stalled. I always use startron I believe my fuel is fine. I have read about an issue with the spark plug caps coming loose mine are original could this be the issue? I tried to crimp the ends to tighten but that did not work. It appears on this model I can not buy the whole wire? It's part of the coil. I have to buy the caps ends and splice in. I am trying to make sure I dont over look something small because this motor ran so well after the rebuild. Any thoughts. Thank you very much for your input.
