Troubleshooting low flow from kitchen sink faucet

I just purchased a 99-year-old house in April, and water pressure is fine throughout the house, except for from my kitchen faucet, where this is as much volume as I get, regardless of hot/cold

I should also mention that water pressure from the sprayer seems normal; it fills up a glass of water in about 1/4 the time that the faucet does. So, the problem seems to reside between the sprayer diverter and the base of the faucet arm.

Today I finally got up the nerve to shut off the valves in the basement and take the faucet apart, but unfortunately I didn't get very far. The screen at the faucet outlet was fine. I unscrewed the topmost piece of the faucet assembly, everything seems OK here:

Pulled off the faucet, and now I'm stuck, I don't see any way to disassemble further. Nothing will unscrew by hand pressure, and in the interests of not chewing up thread teeth, I haven't applied too much pressure with the pliers yet.

Any suggestions for a next step? Thanks!

Old galvanized supply lines get clogged with their own rust.
Shutoff valves under the sink can get clogged with debris.

Sombreuil_mongrel missed the part about ample water from the sprayer which would eliminate the pipes and shutoff valve. Not positive but I believe the slotted plastic piece in the center unscrews. The out side brass is probably part of the body casting. By screen I assume you mean the aerator on the end of the spout.

Chances are it's the diverter that's causing the problem.
The white plastic with the two slots is the diverter assembly.
Take a quarter place it into the slots and turn counterclockwise to remove the the diverter.
Take it with you to when getting the replacement.
Reinstall in reverse proceedure.

Jack & canuk are right. The part you need is for a Delta 2400 Series faucet. The part # is RP6073.

Lower the faucet handle to the off position. Check the Allen nut under the faucet handle. Insert an Allen wrench into the screw, if it is still in place. Turn the wrench to the right to fully tighten the handle screw. Lift the handle. Wait to see if the handle drops back down again. If it does, there is an issue with your handle.

I think you should contact plumber for this....

Yes try to insert Allen wrench. If this will not work, try to replace your faucet.
