Johnson J50PLSIG will not start when cold without quickstart in carb. Starts and runs fine when warm.
SOURCE: engine not running
Let it dry out a day or so, perhaps in the sun or a warm place. Try again. If it still won't start, try to find a fuel line or fuel jet and inject some compressed air in to blow it out a bit. Good Luck!

Carbs probably need to be cleaned and re-built. Common problem in outboards that havent been run in a while

Your cabs need rebuild, something is stuck in the carb or air line cracked
If you have rebuilt the carb check for carb gaskett leak that caused and let the air flow in
When to choke is on the air is block and prevent air flow but allowed small amount of air to keep the engine running
After your engine warmed up the heat in the compression burn much faster so you have to let air in by turn off the choke
Good luck

go to an auto parts store and get a can of gasoline additive called seafoam. Read the label so you know how much to add to your 6 gallon tank. This stuff works wonders on outboard motors.
