I am not completely sure about what is the question.
If it were me, I would do the following.
1. Flush out the brake lines. replace all fluid.
(do same for clutch lines just to be sure.)
If the brake or clutch master cylinder has gone bad, you will find out quickly during this process.
2. Flush fuel line.
(empty fuel tank first)
The tank is likely to possibly have some water and rust in it, so I would slosh around the old fuel before draining in the hopes the water and debris will come out with it.
3. Engine
-Drain all of the coolant and replace. (unless you already have the "newer" 5 year anti-freeze installed) in that case just check the level.
-Remove the sparking plugs. If you don't have a plug cleaner, toss the plugs and buy new ones. They are inexpensive and it's always hard to start an engine that has been sitting with old (possibly fouled) plugs.
- check engine oil level and top up if needed.
- use an oil can to squirt a liberal amount of engine oil in each cylinder
- with the plugs still out, use the starter to turn over the engine until you have good oil pressure. (and maybe 10 second more to get the oil that you put in the cylinders on the cylinder walls.)
- Does it have stock points ignition? (or retrofit electronic?) The points may be oxidized and the condenser might have gone bad.
- also the dizzy cap and rotor are likely to have oxidized contacts. Clean and/or scrape the corrosion off of the contacts inside of the dizzy cap (taking care not to scratch the inside of the cap itself.)
- Check for a good strong spark by grounding a spark plug to the engine (just touching the block should suffice) and have someone turn over the starter. If the spark looks good, put the new plugs in the engine.
- You will need to prime the engine by filling up the carburetor with new clean petrol. An easy way to do this is to squirt it into the bowl vent to fill up the bowl. (if you have already replaced the original mechanical fuel pump with an electric pump, just turning on the ignition should get the fuel pumping.
- buy a can of "starting fluid" (don't breath it, it's mainly ether and you might fall asleep on the job!

) A couple of shots in the carburetor before starting is all you need. (Do not spray while starting)
- be sure you are out of gear and in neutral and start it up!
OK, Guys, did I miss anything?
