This motor was taken out of a trainer, it turns over smoothly with strong compression. Glow plug ok. All four bolt holes show no wear indicating this motor has only been in one model and has been mounted properly. It has a custom stainless extension on the silencer. The throttle arm moves with an easy smooth throw. Would be an excellent entry motor for a trainer but could equally power a fast sport model. The prop is not included. Postage will be at cost.
