Default Throttle Return Springs: Who uses them?

Hey guys,
I made a throttle return spring out of a rear exhaust spring and noticed that it causes the engine / chassis to flex slightly. I cannot use anything with less strength since then it won't close the throttle.

Is this okay or should I find a way to fix this? Also, is there any "real" need for a throttle return spring?

Default the fix

Use a good quality coreless throttle servo and a light spring to do the job. You will answer your own question of the linkage falls off the carb. Nothing like WFO into the outside wall. I have had some trouble with some digital servos for throttle. I still prefer analogs for this job.

Be sure you are cutting power. It wont return with power still on of course.

Attach the spring to the carb in stead of the car itself. Then you won't flex the chassis.
