Friend of mine brought his banch over last week. He was trying to pull start it behind a car. When it wouldn't start, he left it in gear and kept the clutch pulled in. After a couple of minutes, he said he felt something pop. No tension on the handle. I can freely move the clutch arm on the case. What can I expect when I pull the clutch cover? What would have broke? Clutch arm, Adjuster, or is this what happens when the rod welds itself to the ball. Thanks in advance for any help. I've replaced most of these parts on my bike as preventative measures, never had anything break.
