I have a 84 Evinrude XP100 V4.<br />Mod: E100STLCEM Ser: R 08160584<br /><br />When I checked the spark plugs after a day out, One of the plugs had its gap completely closed.<br /><br />So I replaced it and tried again with a new plug, and again it closed.<br /><br />I am assuming the piston is...
My Evinrude 100 will run fine when the cover is off, but when I put the cover back on it loses power and sometimes completely stalls.<br /><br />Any sugestions?
