Hi Mike
Did you make the turn at the bottom of the driveway or go up on the neighbors lawn.
You are right about the issues with brass and aluminum pistons the company that I've used to sleeve all my cylinders over the years was aware of the issue when I asked, response I got was that they are very particular about the actual alloy mix of there brass and also with its purity.
So far so good I've had no problems with pistons sticking or corrosion.
