I have a nice 3W 275 for sale, twin spark, in excellent condition. Also have props available if you're interested. This engine starts and runs great, lots of power. I sent this engine into Aircraft International last winter for service, Gerhard replace both pistons and rings, runs great, starts great. 2 flips choke on, 3 flips choke off (if you're man enough) lots of compression/lots of power.
