That engine has fixed high speed jets.<br /><br />The only way to change the fuel/air ratio is to rejet it.<br /><br />What symptoms are you trying to address?

Re: JOHNSON 115 V4 AIR/FUEL MIXTURE

I was thinking about the fuel/air mixture because i have found a tester that check the correct ratio for carburetor systems and as my engine works not fine and spend a lot of fuel, i thought in this procedure.<br /><br />Also i must test all the ground wires and the resistance and voltage of all ignition components because in this summer, during my holidays in the sea, i have had a lot of problems with the engine.<br />Suddenly and sometimes, the powder full down like the motor works at 2 or 3 cilinders. I inject more fuel pushing the key swich and was bad for the results.<br /><br />I was looking by this very good forum and friends and i suspect that is for a electrical problem with the wire, power pack or ignition coils.<br />I remember that when i was preparing the motor for the winter storage saw a blue/green corrosive contact in one of the power pack that only has one of the two screws.<br /><br />Sorry for my bad english and my mechanical comprehension, but i'm very interesting to trouble all my engine problems.<br /><br />Thanks and regards

I think you are on the right track checking all electrical connections and grounds. Be especially diligent about the coils and their grounds. Clean them very good and see what happens.
