Btw: If the wire diameter, spring diameter and materials are the same, the spring with the less coils (green circle) will be a lot stronger, but will have less travel. Based on the law of Hooke.

Hookes law: F = kx (F is force, k is spring constant and x is distance travelled.)

It would have been interesting to test the springs with a weight to determine the k factors.

Too much math for me 😁

I did consider putting a weight on the spring to compare, however just pulling on the two to compare, the new one has more initial tension, which is needed to make sure the throttle closes fully, in my case.

Maybe if I put it a different way?

Does that help?  

Circular leverage.
