carburetor float control spring?
Date: September 13, 2021 06:08PM

Is the float control spring necessary since my '62 does not have one? I discovered this while replacing a damaged top portion with a '64 top top portion.

Nessesary....no. GM would have never spent the money if not an improvement. Or hung on to the mod. thru 65-69.

You are saying that it is not necessary, but is an improvement. I have the option of putting the "springless float" back or using the float with the spring. However, this would create a situation where one carburetor has the spring and the other carburetor does not.
I am leaning towards the springless float to keep both carburetors as close to the same as possible.

What is your recommendation?

Keep them both the same.

The spring has the effect of making the float "lighter", and able to react quicker
to changes in fuel demand. And as a result, maintain a more accurate fuel level.

Spring is not used with the large float (60 to 63). There is no hole in the float cross shaft for it to work. Spring only used with small floats (64 to 69) where there is the hole to stick the spring end into the float assembly.

I'm with Joel, make the carburetors as similar as possible!winking smiley

Got it....it all makes sense. I'll use the springless larger float.
Thanks.
