This auction is for a little different new vintage OK Cub .049 or .06 DIESEL model airplane engine. Outside is the same as a 049 and not marked on bottom but I think they experimented with a 06 diesel but maybe just a rumor. Diesel head looks different then the usual OK diesels. Includes Kaysun prop and needle. Turns and has good compression. $5.00 shipping U.S. $15.00 shipping Canada. $20.00 International shipping for all other countries. I combine auctions to save you money on shipping. I am clearing out a massive estate with lots of new and lightly used gas, glow, diesel, 2-stroke, 4-stroke, single and multi cylinder engines, tether cars, old radio gear, RTF airplanes and vehicles, and lots of new parts along with used and parts engines so stay tuned to our future auctions.
