Engine shop woes

Yes that does make sense but it doesn't mean they can get it. They must have receipts somewhere because I'm sure they don't stock everything. If they can't get it I'm going to ask them to tear it down and get me all that info. Which I'm sure they won't!

On a side note I can't see any sort of grind or drill marks on the rotating assembly. Of course I can't see under it that well but I will be asking them to show me where they balanced since bit is something I paid for.
