my first engine will only run off of my gas stove when its on medium and only 100 rpm at the most. could this be my displacer is too small? i plan on making another engine that uses sheets of cork bolted together as a displacer.

Engine Timing
Pressure Leaks
Temperature Differential
Friction
Thermal Shorting
Design Issues
