i have a 1989 evinrude 60hp outboard motor that is hard to start when it is cold on some days and it doesn't matter if there is load or not. but once it starts and warm up for for 30second or more, it works great. i have rebuilt all 3 carbs, fuel pump/solenoids, checked compression, changed out plugs, checked all wiring for bad contacts and coil packs, all checked fine. doesn't overheat or stalls when working. i run premium fuel. i am lost at this point, anyone have any idea to where to go from here. thanks..Sean
