Thanks Av8tor,

For comparison, I have a Super Tigre 90 glow engine that hasn't been run since 2005 (12 years).

Last night I took off the glow plug, loosened it up with a heat gun, and did a light flush with some automatic transmission fluid.

This morning, I put the glow plug back on, primed the engine, and hit it with the starter. It started on the first flip.

These glow engines are amazing.

However, I did spend the next 10 minutes cleaning the residual oil from the glow fuel off the airplane.
