70 hp Johnson hard to start.

Here are the parts schematics, but you need the proper engine model number. The best way is to go to a local Johnson outboard dealer as they will has all the diagrams

That tube has a common name, but this website's profanity filter will probably not allow it. replace the two '**' in this Google search link with 'ee'.

At the bottom of the page is this, which will also get flagged by the profanity filter. Add ' pp ' instead of $$.

Hi ,check the needle and seat in the carburator it may not be not be cutting off the fuel when the carb is full as this can cause flooding into the throat of carb

possible loose, bad or broken electrical contact that is cutting off current to vital part of the engine.

Did you try E to aux and x1 to c. Good luck

Ihave a 1991 70 hp Johnson outboard thats hard to start the first time but starts good after that. Seems to be flooded. Starting rpm seems to be low.

Hi, You did a good job of assessing the problem. It sounds like the float valve in the carb is the likely problem. This would overfill the carb when sitting, flooding the engine and the pressure in the bulb pump would go down as the fuel leaked out. Float valve should be investigated and that should Fixya!

With the upper plenum removed and spark disabled turn on the key and allow the fuel pump to prime while watching the fuel lines from the back of the intake to the injector. I suspect you lines are leaking. Have seen this before. ALOT.
