Then again reading through all this brouhaha it's just automatic vacuum valve probably spring loaded flap or something similar. It takes some vacuum in the tank for it to open. While not a problem for new engines might be too much for old fuel pump.

Okay so it is vented, just a new design. Never seen one of these, so no idea how robust the design is.

As SIBRider says, cracking the fill cap takes the valve out of the equation which simplifies troubleshooting a bit.

Will the thing run if you keep pumping the primer ball? How about turning the choke off (assuming it's manual) after a couple of cranks?

Do you use clear gas or E10? Old engines might not like it either. Prob won't happens so fast though.

If you suspect it to be a fuel diaphram issue.

Raise the fuel tank as so it is higher than the engine will cause a syphon affect reducing the need for fuel to be sucked through the line.

Or if you suspect you flooded it. Remove the plugs, clean them up and try again.

*I even used to heat the plugs up using a lighter to clean/dry them off.

Also make sure you have the kill cord plugged in.

Working on it now. I think its fuel starvation. The West Marine tank/hose/fittings are blocking fuel. Primer ball is hard and does not appear to pump. I crank over for a while but plugs are bone dry. The West Marine hose has those crappy two prong fittings but I had to swap out one that mounts to the engine because Suzuki uses a different kind. For some reason I don't think it let's fuel pass through.

I think the issue is the overpriced $25 Suzuki fuel hose connector that Worst Marine sold me. I had to buy a new connector because the Suzuki had a different firing than the two prong connector Johnson uses. When I push in the pin and pump the ball fuel squirts out but when I connect it to the motor the ball is hard, doesn't seem to pump and the plugs are dry despite several starting attempts. Sounds like I may have to replace the hose/motor fuel fittings. And yes, hose arrow points towards the motor.

Yep that was it. The WM fuel connector connects properly to the Suzuki fuel connector (motor side) but will not allow fuel through.

If you got a Tempo priming bulb, ditch that at the same time. The one I got wouldn't even pump air (squeeze, bulb collapsed and stayed collapsed.)

Bulb only primes fuel pump. It should get hard when engine is not running. Disconnect inlet hose from fuel pump and see if you can pump using bulb. If you see fuel coming out that rules out connectors etc. Avoid having open flame nearby at that time.

It was definitely the WM connector. I removed the fuel connector mounted to the Suzuki and plugged it into the WM one on the hose. If both connectors are successfully connecting (but not connected to the fuel line on the motor end) fuel would squirt out the end of the connector, right? Well it didn't. I ordered the Suzuki fuel connector that is the correct one according to the parts manual. Will test when it arrives end of the week.
