That's what I'm confused about. I can't exactly say either way whether it's making a difference, but it failed a pressure test. It's a knock off pump so that's my suspicion.
Ok an update. Here's what I've done.
Replaced the power pack. There was 0v from the power pack to the coils using a DVA. Now the boat fires right up, practically the first turn of the key. Replaced the spark plugs. They were NGK, got the proper champions in there and correctly gapped. Now...
Called CDI, they said to DVA the coil wires out of the power pack. If below 150V, replace the power pack. They had nothing, so I guess it's the power pack.
Despite amazing wisdom to the contrary, I ordered new reeds. The service manual says an allowance of 0.010" is ok, but I had read elsewhere that if you see light through them they are bad. I figured I was already in there so... I had to order new intake gaskets anyway to replace the ones I took...
Yes it was, but I will check again. The key and keyway are fine, also. My timing light is old, so who knows, maybe it got crossfire interference. I haven't been able to replicate it since then, and I don't think a powerpack would cause that.
I know, it's supposed to be pretty uncommon.
I checked for debris; nothing there, they are clean. Like I said, just the first cylinder is leaking, but it does it consistently. And that's the one with the reed hung open, even if it's a pretty small opening.
Actually it's 0.010". So what you are telling me is that crankcase pressure, even very high pressure, should be allowed to vent through a carburetor, even when it does it on no other reed box besides the top one? That's hard to believe.
All the other reeds are sealed tightly against their...
I think I'm going to replace all of the reeds. Any suggestions or just go with stock? My DVA comes in tomorrow so that I can double check everything else. Wouldn't surprise me if there were multiple problems.
