I just played the video.

You have 1 blown out rotor.
I can hear it in the starter gear noise from the very uneven compression surges.

The only other cause I can think of is one chamber has no spark and is flooded, while the is trying to run.

sounds like a compression issue to me, , basicly sounds at least two chambers with very low compression. do a compression test first!

thats what a blown rotor sounds like!? i guess that means I had a blown rotor


I am rebuilding my s5 n/a right now because of a coolant seal leak. thats what it ALWAYS sounded like when I started it in the morning. I had to hold the throttle during that stage, then it would jsut kick in suddenly and roar to life! cool
