welcome aboard
my guess this is a new to you boat
your pinto based OMC motor is not a 2-stroke, so there is no oil needed to be pre-mixed
the dwell angle is 32 degrees +/-2. that would be about a 0.018 point gap. however use a dwell meter.
timing is then set to 10 degrees BTDC
how is the stringers, transom and floor?
