Hi All:
I had a trouble-free summer with my A4, until I went to winterize it on the hard today. It's been idle for maybe 6 weeks. It turns over but never catches. I thought I couldn't detect a spark, and had a new coil handy, so I replaced it and confirmed its supply voltage. When I take a spark plug out I can see a spark (though it looks a little wimpy to me).
Since it was cranking for a while, I would expect to see it wet or at least fuel-smelly when I take off the little screen on the carburetor air intake. Shouldn't I? It's pretty dry.
This is in a 1960 Pearson Triton, and the fuel filter and pump are pretty hard to see and reach. I confirmed that the fuel filter is full of fuel by loosening the screw under the cup and getting it all over my hand, something I could do by touch instead of sight. My uneducated guess is there's something wrong with the fuel pump. The fuel pump is disc shaped, so I imagine that means it's a diaphragm. It's the older engine, and is probably original with the boat. Can people suggest the easiest way to confirm a problem with the fuel pump?
An alternate explanation is that it was an electric problem, but I was dumb and cranked it too long and now there's water in the cylinders so it can't catch even with a new coil. Would that have the same symptoms? I squirted WD-40 in the aft cylinder, but not sure how to proceed here if that was the problem.
Thank you all.
