Which Sparkplug???

[walsalx5151]

What kind of spark plugs should I use in my 1951 Evinrude Sportwin mdl 4423 3.3hp? Is their any specific plug number I should use?

Walsal, Champion's website will say J8C, but as Middleground pointed out yesterday on another post these are a little hot, I would recommend the J4C by Champion, gapped at 0.030".<br /><br />Hope this helps. David
