Is anyone running their throttle return spring from the front of the carburetor instead or the rear?
I would like to move the throttle return spring from it stock location pulling from the rear to pulling from the front. I have read (lars) if you pull from the front it will reduce wear on the throttle shaft bushing. I have a RochesterQ-jet.
If you have the throttle return spring pulling from the front could you post pictures of your set up?
I have seen where some fellows run a throttle return spring in the front and rear for different reasons.

My original 327/365 motor throttle spring was from the front but I changed it to the rear when I installed my 383 stroker motor as I think it looks a little cleaner.

Just want to clarify my post above. What I meant was some run 2 springs at the same time front and rear. I would guess as a precaution in case one spring was to break the other would pull the throttle back.

On some of my old hot rods way back when, we used a dual spring with one large diameter spring and then a smaller diameter spring inside the larger one for exactly the same reason. If one broke, you had a safety spring to keep the throttle from sticking open. Now, I never raced or anything like that but just in case I wanted to I had the extra spring.
Currently I am using a stock single spring for a 73, pulling from the rear.
I have a very light peddle. I do not have any problem with the throttle closing when I remove my foot. Just thinking about something different that might make things last a little longer. I have notice after 1973; Corvettes used a duel spring setup, Smaller one on the inside of a larger one. I agree it does look cleaner when pulling from the rear.
Jessie, I am going to have to take a look at what is on my '73 as everything there is still original. I just need to find the time to take the cover off. Believe it or not I haven't had any of my Vette's out this year yet and in the last few weeks it seems like it rains almost everyday anymore here in N.J.. Hopefully sometime this weekend I will get one or the other out. The only not everyday vehicle I have driven this year has been my Street Rod twice. I have been messing with my '87 SS Monte Carlo I am looking to restore lately out in my Pole Barn as I took that out from under cover. Just too many things on my plate lately. Since my father passed 6 months ago everything has been about his Estate it seems anymore not giving me much time to do anything fun.

Pulling from the rear wears the Rochester base i the rear. Pulling from the front will wear the base in the front. The 'soft' metal the base is made of will wear in any direction that is one reason why the bronze bushings are installed. If you want to minimize the wear have one spring pulling forward and one rearward. In 73 here was one spring and in 74 two springs, one inside the other pulling towards the back. Roger

My understanding is to install a spring that pulls from the front which compensates when the throttle cable pulls from the rear making all things equal. Instead of both spring and cable pulling from the rear.
but just in case I wanted to I had the extra spring.
