    Need some more info. simple question.

    Serial# 1b785368
    what spark plug gap tool do you use?
    I know its been said by Don in the past and others to use the round wire type feeler gauge.
    Which ones are you all using.
    Just trying to cover my bases with some issues and have read that flat feeler gauges are not the right thing to use. So I want to get the correct one.
    On my motor going by the FAQ topics i need a gap of .042-.044
    I found this one but it only goes up to .040
    <Announcements>
    Is this the style you all are using?

    <Announcements> would work if you set so .040" passes but .045" doesn't.

    Any wire-type gauge can be used, via the "go-and-no-go" method.

    Just as a reminder- we don't support the 'zon (or items purchased there) in this forum.
