After reading about both of your engines, two high quality brands, you need to run them more and worry about them less.
well I put a gallon threw the Rossi and I am seeing a steady drop in rpm. We will see if your right about the Webra. From what I know pistons don't grow and if it was a ringed engine I think I would be more optimistic.
I really think what's needed is better quality control.
