Defective clutch lever arm on new kit? Help!

Just purchased an 80cc kit from PowerKing (you've probably heard of them) and have 2 questions.

I haven't installed the engine just in case I need to play the warranty/defective part return game.

First, the fuel float bowl casting is very porous, looks like there might be a crack in it/casting imperfection from a burst hot molten aluminum bubble during the casting process but I'm not sure if it will leak until I actually put fuel in it. That's the best I can describe it. Anyways if there is a slight leak I can fix it with some JB Weld or something similar so that might be helped. But my big concern is the clutch actuation arm.

THE MAIN QUESTION: The clutch actuating lever seems to have a very large sweep/freeplay. Looks like it's a 45 degree sweep. Is this normal? Also it is very wobbly as though there should have been some sort of a bushing between the shaft that goes into the engine cover case and the cover casting. I've attached 2 photos to illustrate my point of the sweep of the arm before it comes upon any resistance..

Oops, sorry, have to properly resize my pics again. BRB

Here's the proper resized pics.

And here's the casting imperfection in the bottom of the float bowl. I took the bowl off and I can't see any light through (LOL) so it might not leak even though the wall thickness in that little area is probably infinitesimal.

Thanks for the reply. Yup I know what you're saying about the lever being in line with the wheels (the position it would be in in the pic on the left) when in operation. And when I pull on the lever (towards the cable guide thingie) that's about the time when I start encountering lots of resistance, as I imagine I should because that's the time when the clutch mechanism starts being operated. It's just that from my experience with dirt bike engines long time ago and how their clutch levers operate I didn't think there would be that much movement/sweep in the lever of this kit and so I thought there perhaps was some stop or override that should be on the innards of the clutch rod that isn't present on this engine. It's good to hear that you have the same play in yours though.

Thanks for all the info and input 2door.
