THis may be too simple but it has happened to me. Did you accidently pull the kill cord?

Been there. The float is stuck inside the carb, or somethings plugged up inside the carb. My 9.9 Merc 4stroker had this issue. Buy and install a carb re-build kit, or have a mechanic do it for you. Don't "clean" the carbs, as the damage is likely done and it will happen again. I wasted time tearing it apart, cleaning, etc..to only find the carb kit was the answer and it runs flawless now.

I had this same thing happen , mech said tap the float bowl real hard, it worked , the needle valve was stuck , only time this ever happened,
JO,
Be sure that you are getting spark on all of the cylinders.
PUll the plug wires off and hold a spare plug - with each plug wire on it, and spin over the engine. Make sure that you are getting an excellent spark from each plug wire. If you are getting good spark, you can be sure that the kill switch is on correctly, because the pulled kill switch - removes spark from the engine.
If you have fuel to the carb, but no fuel to the engine, your carb or injectors need an overhaul so that the carb or injectors will get fuel to the cylinders.
Take care
