i recently got a 4stroke yamaha 426 in a warrior frame. i've been riding 2strokes forever this is my first 4stroke and i can't start the F'n thing

i've tried with the choke on and with the choke off. gas on gas off. i know it's not the bike because the guy i got it from started 1st kick right in front of me and i rode it around the block, so it's user error.

i also am pulling the decompresion lever right at the top of the stroke and releasing before i kick it. any help would be great.
