So, to start
fuel on
Left lever up [retard like everyone said]
right lever down a bit
key on
push button
pull out choke [and almost immediately release]

Once started,
left lever down half way to 9:00 [ up is 10:00, down is 8:00, almost]
right lever back up enough to keep engine running
once warm, at about very steady level 40 mph, move spark lever to position that seems to make engine the 'happiest'. Should be at about 9:00-9:30. Thats where to set spark lever for vast majority of driving.
