Throttle return spring on CW Sprint

[Allan Webster]

I posted this in general gas oval.

I'm freshening my entire car up for the new year and am putting it back together. I had been using a large o-ring from a traxxas backplate around the throttle arm and the intake.

Was wondering how you guys typically set up the return on a slide carb. I'm looking, don't see a good place to attach it?



Thanks in advance,
