It is for lengthening the throttle cable on a grass trimmer that I'm
using for a project. I tried straightening a wire, but it needs to be
perfectly straight so that it doesn't act like a spring. Under
stress, the engine sputters rhythmically. I'm sure it's the wire
acting like a spring.

Then I will need to find a sheath, but I will go for the wire first.

Thanks.

How about the throttle cable and sheath used on Lawn movers etc.
