NEED HELP with 1979 40HP Johnson

[huntandhook]

Hello, <br /><br />Can anyone tell me the proper spark plug and gap for a 1979 Johnson Workhorse 40 HP? The model # is 40R79E which I believe stands for a commercial 40 horse motor from 1979. However I cannot find any tune up specs for this year and model. The manuals I have checked (Clymers, Seloc, etc) only show 40HP Johnsons from 1973 - 1976, and from 1985 and up. Any information about where I can get tune up specs for this motor would be greatly appreciated.<br /><br />Thanks All!<br /><br />Phaedo
