Larry Jenno, of Nevada, is well known for his reproduction “old-timer” spark ignition engines from the early 40s and 50s. However, his first homemade engine is this .14 cubic inch, single-cylinder, two-cycle model airplane engine built in 1943. He carved the patterns from wood and cast the crankcase, cylinder and backplate from aluminum in his home machine shop. It runs on spark ignition and burns methanol (methyl alcohol) with castor oil mixed in for lubrication. This is the only example of the JENNO 14 that he produced. The engine is 3″-long, 2″-wide, 3″-high, and weighs 8 oz.
