Wojtek,

The small dents in the can that occur from ounting lugs are normal and fine. They will not effect the operation of the engine at all, and are just cosmetic. Some guys wrench these engines down a little too hard and will cause the small dents (my original P-120 is the same way), before we learn they only have to be snugged down and not tightened beyond belief.

You have no worries my friend. Bolt that engine in place and enjoy.
