4160 Holley

[dbatteiger]

I rebuilt my 4160. Float question. Primary float was good to go. Level. Secondary float inverted bowl was a little higher than level from the floor of bowl. Directions that came with rebuild kit illustrates level. What should secondary float be? Boat runs fine. Should I leave it as I found it?

Disregard I found the answer

Dry Setting for Duracon Side Hung Float:
The primary side setting is .2188" (7/32"), measured with
the fuel bowl inverted, at the toe of the float. The secondary
side setting is .3125" (5/16"), measured with the fuel bowl
inverted, at the toe of the float.

Tried to respond to your PM. I don't know any detailed info about carbs. Always ran mine at recommended settings at relatively low altitude with great success. Good luck!

Holley spec is to have the float level. In my experience, some carbs don’t like this so I set mine slightly low (slightly high when inverted).
