[3D914]

Been getting my son's 924S running and hit a snag with the clutch. Already replaced the slave, master cyls, and rubber hose between. Checked clark's page and measured the travel. It measure 17.5-18mm. Haynes says min is 15mm, so I should be good.
Looking in the inspection port with the pedal depressed, the arm gos all the way forward and just touches the bell housing. I have adjusted the pedal rod as needed with very little free play.

With clutch in (not running) it will shift no problem between gears.
With clutch in (engine running) get a little grinding and have to push the pedal to floor.
With clutch in (engine running) in first gear, and press on break, idle drops and engine dies. Hear a pronounced brushing sound (not metal grinding).

Recently installed the engine, used clutch disk (in spec), and splines had only minor wear. Fork didn't appear bent, but don't have specs to verify any measurements.

Is there anything else that can be checked before I pull the tranny to help identify problem?

TIA,
