1975 mercury outboard 650

by arwin

was backfiring. the flywheel has 4 dots no sticker. timing belt broke - old age. after setting #1 tdc to plastic pointer on flywheel. where does arrow on belt pulley point. dot to the left is marked timing belt. dot on right is marked #1 tdc. 2 dots in middle unmarked. I guess 27 deg and 23 deg ??? I measured the dots from right(#1tdc) to left(belt timing). dot to the 2 dots 1.5 in. between the the dots 5/16 in. from right dot to left dot 3 3/8 in. need help to setup timing #1 tdc with the timing belt pulley.
