Oldsmobile/Buick Repair: 1984 Blazer, rodent damage, vacuum leak

Question
No, there is on water in the fuel.

Answer
Gee Roger, could be any one of several things.
Distributor fly weights stuck, vacuum advance not working, vacuum leak, rodent damage to hoses or wires, low fuel supply, stuck carb float, choke not working properly.
I'm sure there are more possibilities.
