2 Fox model airplane engines and 1 K&B 6.5 engine. All engines turn over and have compression. I was told they have been sitting for a long time. [they were oiled up pretty good]. The 2 Fox engines seem the same but have different heads and carbs,Also one is polished and the other is not. No glow plugs in the Fox engines,[K&B has a glow plug]. Nothing broken or cracked that I can see. They may be either the Fox 40 - 45 or?? There is one muffler which fits either Fox engine. Fox engines are un-marked but I'm pretty sure they are Fox engines. K&B engine is marked. No muffler for the K&B engine. All 3 engines are used. Sold as is.Buyer pays $10 shipping. USPS-Priority mail med flat rate box.
