[QUOTE="Brider, post: 325082, member: 12510"] I have been browsing posts on here for the last few months as I got my 12’ tin in fishing shape, this is my first time posting. I have a 74 evinrude model 10424S. The motor idles well but occasionally at half to full throttle it kicks hard repeatedly. It seems as if it is possibly misfiring, cutting out then instantly back on. I have new NGK BR6HS plugs gapped at .030. The coils each have a small crack on the side and the spark plug boots don’t seem to have a very tight connection to the plugs, but I am not sure if this could be the issue. Father in-law had this motor for 20 years before me and said he never had this issue although it sat the last 5 years or so. Any help would be appreciated. [/QUOTE]
