Yeah fair enough. Its good your old man wants to get involved.
Just give it a good clean up and try and get it running etc. You will learn a lot that way.
Oo now's a good time to ask this then, are the old torana engines okay to just pressure wash down? or will that mess with the electricals?
i'll most likely wash the rest of the outside of the car with truck wash, in the shade of course
BTW: grats on 1000posts haha
cover the carb and dissy (the round thing with thick wires coming out of it)
with a plastic bag or you could spray with wd-40 or ccr 50/start ya bastard
or even some solvent based degreaser if your desperate
to stop water getting in where it shouldn't be
but yeah so long as it's not disassembled yet you will be fine
if it don't start just take the cap off and dry/spray some wd-40 in and replace the cap and it should go again
