Hmm...the steel fuel lines are there but...............
That doesn't look like an engine from an '82, more like a '78-'79 because of the airpump. Give us the stamped engine number located on the case next to the right fan post. Use a light, it's hard to see. Should be 930/16 stamped, not cast.
Before anything, get the books and read, read and read some more.
There is way too much to be done before you start the engine.
Do more search on this board about starting a stored engine, lots of info.
I know you are impatient to start but, if you do it wrong, you'll be sorry.
Drain and clean the tank, blow out the lines to the accumulator/filter.
Install new filter. Drain the oil out of case and tank. Get new oil and filter (~8-9 quarts 10W30 is enough to start)
Remove plugs and squirt a little oil into the cylinders, turn the engine over by hand (Large socket on the fan pulley and squeeze the belt)
Spark plug socket is the standard 13/16" with a 5" extension. If the tool kit is there, you might have the right plug socket in it.
Be prepared for lots of work to be done.
Hopefully, the fuel distributor and injectors are not clogged.
When you finally start, do a compression check to determine the condition.
Read the books first and do more search here.
