The engine needs a good soaking with some penetrating oil or even glow fuel. Pull out the glow plug and fill the cylinder. And fill the carb if the throttle barrel will turn. If it won't, fill the venturi and let it soak.
I'd replace the fuel tubing. Just make sure there are no leaks.
Your servos are probably okay, but I'd ditch the old AM receiver and transmitter. Replace it with your full range 2.4 radio of choice.
You will also need the usual glow starting gear, a glow plug heater, fuel, electric starter to make it start easier. If you haven't messed with glow before, I highly recommend finding someone with glow experience to help out. If that's not available, jump on YouTube and watch some glow engine videos.

How much time do I have on one of those? Change the radio. You can Crockpot the engine but see if just putting it in a 350 degree oven with a wood prop on it will loosen it up. Wood because I tune plastic props with a heat gun but wood don't bend until much hotter. Heat it, dribble some fuel in it and see if it won't all turn. Hit the carb while hot with some penetrating oil and let it wick into it.
Get everything moving, pull those goldenrod's out of their sleeve and put pushrods into any exposed sleeve and screw in the last piece. You don't need to use a full pushrod, just enough to get an inch or so into the sleeve. It's a stress point and I've seen sleeve bend while control surface doesn't deflect. Really, that's just personal preference from experience, just keep an eye on em.
Anyone remember the promo video of these things? Flying them into junk cars at the junkyard, strapping them with explosives. They were tough stuff. I've built a couple SPAD winged versions of them. Something relaxing about 3 channels simple, tough flight. But I fly control line and Free Flight Monocopters too so I'm a little screwy.

K&B? YUCK! Almost as bad as an Enya. If you have to invest more than 30 minutes to free it up just pitch it. If you have a local club and a person that can teach you how to tune an engine, check EBAY for a .36 size Thunder Tiger, Magnum or O.S.. You don't need a .40 or .46 on those. I taught myself how to fly using a Dura-trainer that had ailerons and an O.S. FP .40. those old engines had simple carburetors and ran easily.
If you don't have a club or just want things easier, go electric as pgerts suggested. Although I'd suggest 450-500W, shoot for around 1200kV and rated to spin a 10" prop on 3S. You can just wrap a velcro strap around the fuse to hang the battery in the breeze to adjust the CG.
Good Luck!

Cool looking thing...
How much did you get it for? Are you keeping the gas motor?
