RE: K&B .28 piston scoring
I went ahead and ordered a new piston any cylinder from Mecoa. This piston is crap. I will take the utmost precautions with the new parts. I paid $50.00 for the NIB .28 plus $34.59 for a cyl and piston so that brings it up to about the price of a new one from Mecoa. Schtuff happens. Looks like I will be selling some of my other collection to pay for it.
