Had this engine in my 84 Mid West AT-6 for around four years, powered it very well, plane weighed 16 lbs. Crashed plane and now don't need engine. Inlet manifold and rear origional carbon mount were damaged in crash, no head Or other damage, replaced with new inlet manifold, new updated metal back plate and engine comes with new muffler pipe and gasket. Ignition and origional box supplied. Bargain 38cc gas four stroke.
