Question; I have a 1990 Freedom 195 w/ a 4.3 V6 that was working just fine until this weekend I went to launch and the engine wouldn't fire. I went thru every possible troubleshooting. Battery is new and was putting out a full 12.6 volts. Starter was cranking and receiving 11.8 volts. Coil was putting out a very strong spark ( I took a nice shock from it) I pulled the cap and cleaned all the contacts to a nice shiny copper. I pulled each plug wire, they are all received spark.I changed the plugs earlier last week, gapped to spec and test fired in my driveway with an instant rumble. Had half a tank of gas, and sprayed very generous amounts of starter fluid into the carb. Still engine wouldn't fire?? I had never had a problem with it. So got to thinking, there is a black button above my ignition, is this the lanyard engine kill safety switch? I have never used it before and have never had anything attached to it. Did I depress that button by mistake and did it keep the engine from firing? If that is a possibility, what do I do to by pass it or "reset" it? Any info would be so appreciated! It sucked sitting at the marina for 3 hours of troubleshooting in the rain with my brother Labor Day weekend missing the salmon runs!!
