I've got my carb apart in the garage at the moment.. The main jets look like the brass sticks down further but it'll probably fit. The pilot jet looks goofy, like the tip is different all together. I'd send it back and buy OEM or use what you have.
What's wrong with what you're working with? I'm going back out to clean everything with piano wire ;-) my 40 pilot jet was plugged completely shut, but since I pushed wire through it it's totally fine. Nothing ever seems to be as nice as OEM stuff.
