Return spring setup for 4500 dominators?

You can hook one spring to each front wheel and one to each carburetor and then it'll get Tighter and Tighter as you drive that way you'll never have a stuck throttle..

Can you expand on this?

A spring to each lever arm and the other end of the spring to carb base?

If all else fails I will just make something but buying what we kneed is way easier and at some point cheaper.
