I'm using a Tilton 78-Series Master Cylinder # 78-625 (front pivot MC) for the clutch.
Anyone have issues with its internal check valve? I'm getting inconsistent clutch release (both at the track and in the shop).
I've bled the clutch system and set the MC stroke multiple times. Sometimes the clutch releases fine, sometimes it won't release at all.
I have a new spare, and I will replace the one that's now in the car. I'll report back after I do this.
