2000 Johnson 40 won't fire

Getting the 'toon ready for the season & everything looks fine after winter storage. Except now the motor cranks & cranks but won't fire.

The fuel priming bulb is firm. There's fuel visible in the filter. I hear the "choke" click when I press in the key--but I suspect the choke solenoid might be bad.

I finally put a shot of ether in one cylinder and it started immediately & purred just fine. Next day I tried again... Same thing--crank crank crank crank forever. Finally started after 15 minutes of trying.

How do I troubleshoot this problem?

In the picture, is the small tube on the top of the carbs the "enrichment" lines?

Does yours have a start circuit injector solenoid?
My does, basically when ball is pumped it fills the solenoid, and when key is turned it injects a shot of fuel into chamber (like the shot of ether did for you)

If it has been siting I have to turn the bleed screw for solenoid as I pump ball; only takes a second and we are good to go

ETA mine is a suzuki tho'

No bleed screw on the solenoid in this Johnson--just a manual bypass. Turning the bypass also didn't get the motor to start.

There's a Schrader valve in the center of the bypass that's meant as a port for injecting fogging oil. That might serve as a bleed (?) but I've never heard of it being used for that, or needing any attention.

Anyways I thought after finally getting it running on Saturday that I would be golden on Sunday. Nope.

Hmmm...I seem to have asked the wrong question.

Lemme try a different question: What's your favorite rub to use when smoking a pork butt?

the 4 screws on top with the cover to atmosphere, with all the black crap on engine

Whae I took my "cover caps" oss there where a couple small air jets for the idle circuit? mine where clean, maybe that is hiding under the cover?

Just to close this out...Yes the small hose connected to the top of the carb is the primer hose. It was getting no gas. I replaced the primer solenoid. Before putting it all back together I pumped up the bulb & jumpered the primer solenoid wire to the battery feed. The priming hose pissed gas 6 feet and continued until the pressure was gone from the bulb!

Now it fires right up.
