Reving out of control possible causes:

1. Bad IP internals or external (linkage stuck?)

2. Engine oil level too high fuel sucked in through the rings.

3. Too much blowby getting into intake.

Not sure if a torn IP diaphragm dumps fuel into the crankcase. If so, check oil level and if high or smells like diesel you found the problem.
