/diy/ - Do It Yourself

Hello friends. I'm a newbie so please go gentle. I promise not to be dumb on purpose.
I'm home for the holidays and house sitting for my dad, so I finally have access to his tools and shop, and since I'm bored I chose to rummage in some old RC plane parts he's got laying around gathering dust.
I decided to disassemble and clean one of the small engines in the box, and have managed to get it almost all the way back together, with the parts able to move where they were seized up from schmoo before.
However, I don't know how to get the motor running. I have a small bottle of "molecular fuel", some fuel lines and a small tank, as well as a handful of servos and old battery packs I don't know the quality of, but I can't seem to find anything resembling an alternator or spark source, which would go onto the top of pic related, which seems to be a kind of spark plug protruding from the inside of the cylinder head.(?)
Does anyone have an idea what I'm missing, and if I need to go and buy new parts or if there is something I should look for in the mess of a box I found this in, in the first place? Thank you so much.

TL;DR: how to give spark to small rc motor? Also cocks.
>And yes I made the soft jaws for the vise out of wood first because I didn't want to crap up the little engine.
