No, you probably ordered the wrong kit. It will cost you something to ship it back the way they want and it may cost you money to re-stock it etc etc.
You have to be careful when ordering carb rebuild kits.
As an example, certain kits (moose I believe) come with the wrong thread pitch air screw so it's basically useless. In that case, that is a aftermarket manufacturers issue but your still stuck with paying the return shipping and possible restocking charges.
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
