Float chamber cover warped

[phattanglo]

I've been trying to work out where my carb leak was coming from and realised it's the float cover that's warped. I've ordered a replacement and I'm using the one off my son's px200 for now.
Is it possible to fix the warp or shall I give it up as lost cause.
The two ends where the bolts go touch the carb top but the middle has a gap which allows it to rock from side to side.
I tried to dress the ends with a file but I couldn't get an even surface and probably made it worse.

I suppose you could try and flat it like you would a cylinder head??

What’s the cost to replace??

It was a tenner on fleabay.

Replace at that price.
By the time you muck about with it on off on off.
And it will be on your mind for a long time.
