How To Do It: How to Start a Schnuerle-Ported Engine
The Problem: When Earl Stahl designed his 1941 Free Flight model of the Fokker D. VIII, an Ohlsson .23 was adequate to pull the lightweight model skyward. Forty years later, I wanted to duplicate this model for radio control. Mine was heavier, so I opted for the popular K&B .28 engine. I bench-mounted it, primed it, and flipped the prop. Nothing-it wouldn't start. I mounted a spinner and then used an electric starter. Squeak! It still wouldn't start. Why couldn't I start it? The engine was brand new, but whenever the venturi intake was primed or choked (per the instructions) the liquid seemed to lie in the lower crankcase and then squirt directly into the cylinder and onto the glow plug. Brrrrp-brrrrp. Nothing.
