  • Spark plugs

    Planning to fog down the cylinders .
    You'd have laughed if you'd have seen me looking for the plugs.
    When I found them I laughed. Not my 1982 40hp Yamaha. LOL
    Finally followed the plug wires , removed some screw from the plug cover & looked down the tunnel at the plugs.

    They were barely snug, just over hand tight.
    No signs of blow by.
    Gap was .044 - 45. (book .039 - .043) So ok.

    Gotta get some fog spray tomorrow, may replace plugs too.

    Any plug readers here?
    Look like they need replaced?
