Basic Engine Questions, Firing Order and Water Out the Tailpipe Options

[Highland]

Wondering what the firing order isn't 1-4-2-3 instead of the actual 1-4-3-2. Wouldn't it make more sense to go back and forth between opposing sides? Would the engine sound smoother with 1-4-2-3?

I happen to be by my tailpipe when my engine transitioned from cold idle (~1800 rpm) to warm idle (~1000 rpm). When the rpm dropped water sputtered out the tail pipe and continued compared to dry exhaust while cold idle. I know water is a product of combustion, but does this tell me anything about running to rich or lean at these idle conditions?

I don't have the answer but I am interested in other members responses as I also noticed the water out of the tailpipe after starting up my motor after a motor rebuild .
