You could mount the engine in the plane. Hook a fish scale to the tail ahead of the stab. Start the engine. Rev it up and read the scale.

You would attach a spring scale to the tail of the airplane and measure the amount of 'pull' you get. Make sure you have a large-enough scale to allow up to 10-12 pounds of thrust. This will be good for engines up to about .61 size.
