Hi all Iím currently restoring a 63 40hp Johnson and doing a few mods to it. I came across an old post from Ď07 on this regarding a mod that will advance the timing on these old motors but they didnít go into any great detail. Was hoping someone here can shed some light on this topic. Was along the lines of a brass strap with drilled holes in it. Link to post is below.
