Thermo quad float bowl adjustment

Thank you. Are these from a manual? If so which one? I was wondering about a few other adjustments and just general tuning.
Tad and everyone elseā€¦. Those are general settings that should work just fine. Throughout the years the floats had various height settings. The fuel level in the bowl has an effect on a rich or lean condition at idle and somewhat at cruise. These various float levels were changed year to year and vehicle to vehicle as needed to have the engine just right when new.

Should you change jets and rods around and find that it is rich or lean at idle but not really so on acceleration or cruise, the float level is the issue. Too much fuel equals rich and to little is lean at idle. Even though your changing jets and rods around to make driving good, idle suffers.

Same deal with Holleys.
