RE: Super Tigre GS 45 ABC

Just crashed a Rascal 40 w/ 45 (great combo) due to pilot error. Would appreciate any answers to:

1. Upon engine disassembly, noticed the allum prop hub has run-out. Looks like oem deffect. Suspect crank was dialed & IS DEAD TRUE! Cant believe it. How does one remove alum hub? Should I try to reseat it...or buy a new hub? The spinner backplate did run w/ some run out.

2. Is there a performance issue w/ removing & reinstalling the ABC piston / sleeve??
