What are my likely sources of error?
 

So I went out in the perfect weather for offroading today (pure rainstorm)
and hit one mud hole and then go to climb a small gradient and my Jeep
sputters and then dies. I've recently replaced the battery because my old
one was toast and this new one is just a temporary cheapy that doesn't crank
too many amps. I figure it must be the battery, but it seemed to be fine,
and after putting jumpers onto another Jeep, it still wouldn't start. It was
turning over but wouldn't catch. We checked the air filter and the carb was
getting fuel. The plugs were dry. All wiring seemed to be hooked up. The
accessories all worked.

Next idea was to test the plugs. We pulled one and it sparked. Then we
checked the distributor ends but there was nothing there. No spark at all.
One of the guys I was with suggested it might be the electrical solenoid. Is
this correct? I'd rather have some idea what to replace/fix cuz after
checking the stuff I mentioned above, I was all outta ideas. When I was
getting towed home, we decided to try and jumpstart it by dropping the
clutch from 2nd while moving. The Jeep turned over and sputtered a bunch of
times and then backfired.

What are your guys thoughts?
It's a 1985 Jeep CJ7 2.5L 4cyl carb.

Thanks!

LOL, just realized what I wrote in the subject. I've been studying for my
4th Year Research Stats course all day about error control and my brain is
still engaged in that. Ahhhh

I will second that.

Condensation is an issue when the hot cap hits cold water. My CJ7 will
die like that. All it takes is a shot of WD40 under the cap to 'dry' it
out.
