The Vintage 1/2 A class Atwood Wasp .049 glow plug motor is a sought-after engine for model airplanes, specifically those that run on nitro and glow fuel. Known for its quality and reliability, this Atwood .049 model is designed for high performance and durability. 

This item is in the original box, with the spec sheet and additional propellors.  Turns over freely, with compression.  However, be aware the needle valve (see pic) has snapped off; skilled repair is necessary.  The needle valve controls air intake / fuel mix ratio. 

Sold as is.
