Cold Starting 1985 Yamaha Outboard (115 HP)

I know that there is a trick to starting this engine, but no matter what I try I can not get it started. I have replaced the plugs and checked to see if fuel was getting to the cylinders and all seems fine. Fuel is going to all the cylinders and there is a very strong spark. Yet, she will not start. I have tried to start in neutral with choke, neutral w/o choke, full throttle w/ choke and without - still to no avail. Any suggestions?

Try to spray some premix into the carbs while starting

I'm a newbie at this but I'll take a guess,

If you have both spark and good fuel flow then timing maybe off. Was this motor running before then just suddenly became stubborn? Motor needs spark at the right timing to run, maybe you had a back fire recently and sheared the flywheel key. Just my opinion.
