Too many different directions here

First charge up the battery
while seeing if engine will turn over check for spark
if you have spark, spray a little starting fluid into carb while cranking to see it it hits a couple times--if so, timing is close enough to run
fix up fuel system---fresh clean fuel in tank, new filter, check pump out put/pressure, fix carb--a carb kit is cheaper than a new carb/manifold---prime carb, crank engine with starting fluid---- if it starts and runs, warm it up a little and then drain oil/coolant, do general periodic maintaenance--belts,hoses,plugs/wires/cap/rotor---------
