Fuel System: Throttle Return Spring 57 GH

[Mark Klinger]

Help! Need a part # for a throttle return spring for a 57 GH. I've checked the parts book and see several possible ones but nothing specifically for a 57H-K7 with 2 barrel carb. It appears to be fairly short, looking at different engine pics it appears everyone uses whatever works. Well, I'd like to have the correct spring. Any suggestions?

Exact spring tension makes no difference in the '57-'58 GH application, as the 'anchor' point of the throttle return spring is adjustable ( anchor slides up and down the fuel line)....in your photo, your anchor is pushed up against the fuel fitting at the pressure box entry point.

Find a spring that looks right (from old factory photos) and set the tension anywhere you want with that adjustable anchor.

Duh... adjustable anchor. Wish it was all that easy, even had an extra spring I had found in the engine compartment (right side) that fits the bill! Could it be the original? Thanks for the help Ed.

You've pretty much 'nailed' it Mark....the item I'm calling an 'anchor' is the piece that slides up and down the horizontal section of the fuel line....In your lead photo I could see that it was pushed all the way up and resting against the fuel inlet fitting at the base of the carb air chamber....In your second photo you've slid the anchor down to its proper position and, aside from that spring looking a bit 'cruddy', everything is as it should be......WELL DONE!!

Found this brochure page with a 289 SC engine showing the placement. Guess I'll turn the spring around, to be really correct and clean it up while I'm at it. I've even gotten the correct battery hold down and washer bag hanger. Whoopee!

Yes, someone should detail their '57 GH engine like in the brochure, bring the car to a big SDC National, and insist to the judges it's original!!....(I think I'll try it! )

In the Car Show Engine pic, doesn't that look like the Secondary Throttle Return Spring, the Black one from the Valve Cover to the Linkage at the Bellcrank like a Non-Supercharged Engine?
