greetings,<br />I have a 1986 Johnson 8 hp that is running rough. I must keep a partial choke on for it to run. <br />It won't idle otherwise. Full throttle I do not need the choke. It was suggested that I run some <br />Gumout through the engine. This may help clean the jets and let me take off the choke.<br /><br />What is an appropriate Gumout-fuel ratio to use? Thanks.<br /><br />Jim
