Hey Guys,<br /><br /> Everyone here helped me so much just wanted to thank you<br /> What is the best plug to run in a 1959 Johnson Seahorse 18HP.<br /> The mix calls for 24:1, is that changed in this day and age.<br /> Thanks again Guys.
Itec01<br />Original spark plug was a Champion J4J. Today it is a J4C. Good O/B oil (my favorite Evinrude Ram) at 24/1 or 32/1 works great. .030 gap on the plug.<br />Backfire
