throttle return spring

I have a Holley 600CFM on my SBC 350. I had a return spring on it but it made pushing down the petal really hard. I have stretched the spring a little and my petal works much better. How many of you use a spring other than the one that comes on the carb? It does return without the extra spring.
Thanks

NHRA requires an external spring, and for good reasons.

No running a race and I don't have roll bars either. Just want to know what others are doing.
Thanks

I contacted Holley and they said that they would recommend a second spring.
Thanks
