Okay, here's a benchmark you can shoot for.

With your nozzles set at 2 1/2 turns down from full up, start adjusting your float levels so the resultant fuel level rides within a 1/16" or so below the top of the nozzle. Check this by pulling the dome and piston and looking down in the tube with a flashlight. There should not be fuel standing on the top of the nozzle nor should the fuel level be way down the tube.

This fuel-level-in-relation-to-the-top-of-the-nozzle is where the bear and the buckwheat cross paths.......

If it's an L24E, it would have 'P30' stamped on the block just ahead of the drivers side motor mount or 'F54' if it's a 80-83 ZX engine or 'N42' if it's a 75-80 engine. Or look on the side of the block just below the 5 and 6 sparkplug. It should have 'L24' or 'L28' as the first three characters before the numbers depending on which it is.

Just checked, it is an F54 block w/ an N47 head.
