Default Pk80/68.5

I purchased the PK80/68.5 cc from Zoom and got a ZB8os-sr after argue'ing with Zoom,they finnally sent what I think is the Pk80/68.5 jet, but I have my concerns First what does the arrow and # 3 indicate on the piston and since they removed all identification tags from the engine how do I tell that what I have is actually the PK80/68.5 and not 49cc or other brand of lesser quality and if it is the right engine what are some tweek tricks to improove performance?
Will some one shed some light on my situation
