Re: what yr evinrude??
You have a 1956 15hp Evinrude, not a 18hp.<br /><br />Use Champion J4C or J6C s/plugs, set the gap to .030 . The J6C usually give a better idle.<br /><br />Points set to .020 on the high portion of the cam lobe. A fuel mixtuire of 24/1 would be recommended (1qt of 50/1 oil to 6gal of gas). A octane rating of 87 will be fine.<br /><br />Use "HiVis" gear lube.<br /><br />Zoooowwwieee! That JB is fast isn't he.... or was it Ezeke? Got me coming in last!
