Re: Gear ratio ?

My source says 13:26 (teeth), astro. That translates to 2:1 in turns. I am not certain that is accurate for an '89.<br /><br />You can verify that by turning the flywheel until the prop turns one full turn and noting how far the flywheel has turned. If 13:26 is correct, it should take two full turns of the flywheel to turn the prop one turn.
