The Husky 42/42 special/242/246 thread

I have an old 42 piston on the shelf , no special

This is without the 242 "windows" ? Does the windows gain a little power in a 42 or will it just mess things up?

Typically open port cylinders are bottom fed and don't need a windowed piston but the 42 is side fed open port so it would seem that it would benefit from the windows.

I have a Husqvarna 42, the piston was without windows and I installed a piston with windows. Unfortunately, I don't have a comparison because the saw didn't work before. Gilardoni top hat open ports

That's my thought sir. 42 and 246 cylinders seems identical except bore size, so why does the 246 have the windowed piston and 42 not?
