Hi Ho Boating Buddies! 
I have a "new-to-me" Yarcraft with an '84 Evinrude 50 on it. I took it out 5+ times and it ran beautifully. The last time I took it out it died on me...sounded almost like I ran out of fuel but I had just put in 4 gallons (50:1mix).
The fuel bulb was firm and the tank was vented (been there, done that).
The when I try and start it, it will start but it immediately cuts off...again, like I am starting it without fuel.
I took it out of the water and:
- checked that fuel came through to the fuel pump when the fuel bulb is squeezed. It does.
- checked the fuel pump. Diaphragm is in good shape, springs are seated and moving freely.
- changed the fuel line from the fuel pump to the carbs (it looked like it had a small crack).
- squeeze the bulb, fuel comes through to the carbs.
- removed, cleaned, and rebuilt carbs with kits (new needles, seats, and gaskets.) It actually looked pretty good - I think they were cleaned in the not too distant past.
- I replaced the spark plugs - the old ones did not look fouled or anything, just trying to love the engine.
It'll start if I spray starter fluid in the intake but it will not run. I can't help but think it's a fuel problem but I can't see any issues with the fuel system so far (I am definitely not a mechanic...just a gal with some tools and a Sealoc manual).
What should I try next? Help!
Thanks a bunch for reading through all the details.
Cheers,
T
