This is a nice Thunder Tiger 1.30 four stroke. I had it in my Citabria Pro and sold the plane so I don't need the engine anymore. It's rated at 2.2bhp@11,000 rpm. This engine has about 8 tanks of fuel through it. It runs great and pulled my 13 pound Citabria with ease. Comes with original box, paperwork, tools, a 3" aluminum spinner, Turbo Header 90 degree exhaust manifold, and 16" prop. Free shipping in the lower 48.
