I had this motor running so perfect then driving home i shut it off for a secont to see if a fellow boater needed help and it wouldnt start back up. Had to get towed in for my first time. Tried cleaning the carbs and rebuilding them n it starts for a second then dies. Excellent spark in all 3 as well as 135 psi in all 3. Reajusted the timing but not sure how to get it back to where it was. Tried every position but cant get it to run right. Also seen like black oily gas mixture out the prop exhaust from it starting a few times. Any ideas? Thanks' steve.
