Johnson 4 stroke 115 hp will not start. fuel

Does it have spark when it cuts off?

For minor tune-up. Remove, clean or replace spark plugs. Use Johnson recommened fuel additive and recommended fuel type. Replace lower unit grease. Spray clean carburetor. Check fuel line and filter. check water pump function.

lots of reasons check spark again and fuel to what filter carb? engine problems basically are gas and spark so tells me its gas pull plug squirt some gas 2 stroke make shure its oil/gas 4 stroke gas only in cylinder use a eyedropper or a clear gas line of fuel to put fuel in cylinder put plug back in fire up if starts problem in carb if no start may have jumped timing check air filter may even have a mouse nest in it most people don't drain gas out of carbs for winter drop carb clean bowl with pure white vinegar clean all jets pilot / main reasemble

To get the year of Johnson and Evinrude outboards use the word "INTRODUCES". Each letter corresponds to "1234567890" respectfully. It's best to check with a model year reference book, but this motor's model number contains "CC" which would indicate it's a '88.

Do you have spark? What about fuel? Have you tested anything?

fuel goes in at connector then to fuel pump then to carbs ! remove connector off fuel line and prime fuel up so you know you got fuel ! then reconnect to engine and prime up again till you see filter filling and bulb should harden , then remove a drain screw from carb bowl and prime again and see if fuel comes out of all carb drains ! if yes then start engine with or in water with kill lanyard on if ok then good ! not then check sparks on all plugs putting them against the head for earth and crank to check ! if ok then i would remove carbs and clean the jets etc ! compressions 100psi or more on all cylinders ! less means recon pistons etc !

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

Not so many reasons she won't start. 4-Strokes are Simple!

Here they are:

Motor:
Fuel Tank-> Fuel Line-> Fuel Filter-> Carb-> Intake (Valve)-> Piston-> Exhaust (Valve)-> Muffler

Carb (Old Style):
Fuel Side:
Fuel Bowl-> Float-> Needle Seat-> Fuel Ports (Venturi)
Air Side:
Air Filter-> Carb Air Intake-> Butterflies (2)
(Clean 'em ALL!)

Hardware (Motor):
Rotor (Magnets)-> Magneto (Ignition Coil)-> Spark Plug Wire-> Spark Plug-> Cylinder Head (Spark Plug Ground)

Ignition:
Kill Switches (Seat, Clutch, etc.)-> Spark Plug/Ignition Coil-> Ground
Key Ignition-> Battery->Starter/Generator

If one of those fail.......= Non-Starting 4-Stroke!

Fixes-
Fuel:
You are either getting too much, or too little. Too much = Carb.
Too little = Carb. Therefore, tear down the Carb (COMPLETELY-Careful!) and clean it up.

Electrical:
Grounding out the System (Kill Switches)
Battery-> Ignition-> Starter.
Magneto->Plug Wire->Plug (Check 'em all!)
