There is a book(let) put out by the IMAA called the "IMAA Giant Scale Handbook" that has a chapter on converting a Poulan Weed Eater engine to flight-ready. They install it in an Einducker - kind of a giant scale box-fuselage S.P.A.D. A little more involved than just stripping off the plastic and they walk you through it well.

The handbook has other good tips but, unfortunately, has a large section devoted to "currently available" servos and engines - many of which are no longer available and therefore wasted space in the book. Good info on coverings, compatable paints and setting up a pull-pull arrancement (Ackerman Effect explained well).

It's pretty simple to do, but with RC designed engines selling at the prices they do now, it's barely worth the effort unless you just want to. In a nutshell, you make a new exhaust that flows more and redirects the heat down and out of your cowl (pitts type muffler is typical), you cut off anything not needed to mount the engine to the airframe, and you make or buy a prop adapter. It's optional to remove the flywheel and magneto to set up a CDI ignition, but if you do you'l save weight and get more horsepower and reliability.
