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.
