Husqvarna 235 chainsaw Breather Solution

To change the breather of a Husqvarna 235 was a pain in the ass, drilled a little hole in the bronze plug vent, put a screw in it and tried to pull it out with all the force I had, but didn't work.
I drilled more small holes and got it out. The hole was somewhat damaged, drilled it bigger, put a hose in it with a more common breather.

I used drills with 0.1mm in between to make it bigger and bigger until a good sturdy fit was created with the hose.

The saws of your kind and I often fly, and have been repaired many times without solving the problem. I suspect it's the balance valve, but I don't know how to replace and buy accessories. Please advise.

what vent did you use and what size drill bit was the final size? with what hose?
