1981 80cc, help me, electric stuff

i have a 1981 RM80, kick starter broke off, coil is currently off my moped, it looks the same, my dad said it should work, spark plug wont spark, i was told if i push it around the damn plug should spark, so far im only going for the electric part of it to work, then mechanical, the engine is in good shape, sounds good when its pushed while in gear, needs a new muffler, air filter needs new foam, gas tank is internally rusted, the gas filter might let gas through it, dont know yet, hopefully somebody out there has the decency to help me out, thank u
if anyone has a maual for one thatd be awesome too, maybe u can copy a page about setup for wiring
