Have a Tohatsu 2003 70 hp 2 stroke, mis-firing

Customer Question

Hi have a Tohatsu 2003 70 hp 2 stroke, mis-firing intermittently on the top cylinder. I have swapped out spark plugs, injectors, and ignition coils from the adjacent cylinder, and the top cylinder mis-fire persists.
Any suggestions for further checking you may have would be appreciated.
Thanks
Todd
