Noticed the flange on my carb was warped, Resurfacing was needed
This carb is probably 15 years old at least, I guess over the years the flange slowly warped
I don't over tighten the mounting nuts, Over time the flange will just warp on it's own
I figure
1) The fact the carb has an O ring that needs to be lightly compressed
2) The fact that the intake gasket is rubber fiber material that will also compress
3) The fact that heat transfers thru the mounting studs and the wings of the flange get hot
4) The fact that the center of the flange stays cool because air and gas are always passing thru,
This all causes the flange to slowly warp, then the O ring isn't getting compressed evenly and making 100% seal
Resurfacing didn't take long rubbing the flange surface on 220 grit sandpaper/plate glass
Then a good cleaning with carb cleaner to spray out any aluminum dust
For a 15 yr old Taiwan knock off Kie Hin it still works good
