Powermore Carb Insulator

Has anyone come across the carb insulator on a Powermore being warped? I'm working a machine withe A Powermore, that I cleaned the carb and it was still hunting. Put a new carb on still doing it. New gaskets install. I sprayed carb cleaner down by the insulator and it seems to smooth out. This is the second machine I've had this problem.The part is kind of pricey @ $15.

I don't have one of those. But could you maybe use some paper gasket material and cut out something to put on the insulator surfaces, to help seal it better? Or if the sealing surfaces stick up beyond everything else, and are flat, you could lap them on some fine-grit sandpaper on a smooth surface, to help bring them to a uniform, flat surface.

Interesting.
If it's bowed out then a gap will remain after tightening.
Thing about spray... is the fumes are so close that they can make it back to the inlet side of the carb..which will take care of the hunting anyway.
A leak would cause a faster idle or one that went to lean to run.
I can idle my Powermore down very low(all stock settings)
If your low idle is also affected ..I would be aiming towards a leak.
If you know it is bowed for sure..as said above..remove some material.
A flat surface(kitchen table) and fishing line can help you find the low area.
If nothing is in the way on the insulator and you can get the entire mating surface on a flat surface...you could have someone hold the sandpaper on the edge of the table and run the mating surfaces across it
Use two gaskets..cutting the ear section off one gasket would also help ...as the ears wouldn't be bottomed out as soon.

Its a really poorly made insulator. Its made of Polypropylene, which is a horrible choice for this type of part. Should have been made of a harder plastic. I can't file on it much, as it has a slight slot molded in on one side. I just wanted other people to be aware, as it is kind of a frustrating problem to figure out.
