Carter 750 float level

I saw them advertized for off-road use, I'm sure you're right. And they are .0935. The Carter sheet shows both types, but no mention of differing float levels, which was what got me thinking about it. With the float pressed down (or up, I guess), there's just a whisker of light between the float arm and the sheetmetal plate that sticks down from the lid. Mike's Carb is about a 10 min drive from me, could I just replace the needles? Entire assemblies probably aren't that much though.
