Craigslist score

He send me a poor quality picture of the engines and I figured I'd take a chance. I got a nice Norvel .061 plus a new in bag fuel tank/mount, a Tee Dee .051, a Black Widow, a Cox power pod and several new props and glow heads. $35.00 shipped and thank the nitro God he uses PayPal.
The Tee Dee has a frozen head, but I was able to get the cylinder off and there is a dimple in the top of the piston. I don't think I've ever see this before. Any opinions are welcomed.

if you hurry you can get that V-twin Cox on ebay before someone else snatches it up. LOL.  I just posted it.

I have seen the dimple in the head, but I can't remember why right now. It's late and something happens when you get old, but I can't remember what it is. Bet you didn't see that coming.  
p.s. is it a brand new head with a glaze coating on it?

if the dimple was towards the top of the piston  it would indicate the rod was too tight, but it looks like it is dimpled towards the bottom of the piston. The only answer I found, Google, was that possibly there was a gunk/hardened fuel/burnt oil buildup and it protruded downward towards the piston from the glow head??
over and out.
