GT,
Here's the distributor, you can get a pack with the tools and instruction manual from them. http://www.horizonhobby.com/

I'm guessing you got the engine used? Use a standard starting proceedure to fire it up; Fill the tank, 3-4 drops of fuel down the carb, flip the prop 3-4 times (counter clockwise), set the throttle so the carb is open just a crack, attatch the glow driver, then use your starter to spin it, it should go.
I've got a couple of these great engines. When I go to my shop I'll see if I can dig up a spare book/allen wrench.

P.S. USE SOME LOCTITE ON THE FRONT L.G. MOUNTING SCREWS, AND THE TAIL MOUNTING SCREWS!!!
