Default YS63 FZ plunger

I ordered a YS 63 FZ plunger from Central Hobbies, their part# YS1145 as shown on their blowup diagram at http://centralhobbies.com/Engines/parts/YS63FZEx.html. Anyway, the plunger that came is about half the size in diameter as the one in my engine.

YS Parts and Services shows part# YS4405 on their website @ http://yspartsandservice.com/pdf/FZ63.pdf.

Anybody know what the deal is on that?
What is the correct part#?
