I recently acquired a '51 8N basket case and have split the tractor to have the engine rebuilt. While apart I have replaced the clutch throw out bearing and rebushed the clutch pedal. I've attached the throw out bearing hub springs (p/n 9N-7562) and noticed the clutch pedal doesn't return to full up position. The springs are both the same length and seem to have good tension. What am I missing in order to make the clutch pedal return to full release position and stay up? Advice would be appreciated.
