I agree with the ABN theory. After my first Os 46AX peeled it's liner I repalced it with a new liner, piston and bearings even though the old bearings looked good. Was only a few gallons later the liner was gone again and I still had my needle settings rich. I am so disgusted that I parked that plane and bought my first electric. Problem solved!
So much for the expensive quality control on those nice OS Nickel plated liners.. sounds like someone is sleeping on the job, or they got Elmer Fudd doing QC..
