Hi, anybody out there who knows where I can buy a stack and foam filter to fit on my Stihl 026 MOFO ?

No problem, I could fabricate the albow. The stack and filter would be what I need. With the carburettor I have , I would loose the choke function, I think I could live with that.You really can’t.
You need to fashion an elbow.
Thanks for your offer to help, happy about that. PM sentI could probably design something if the choke delete wasnt a big deal.
Been slacking... here’s those pics.
I like this, but as you said, it could do with a bit more angle to the filter. I think "mortalitytool" is trying to do something for me, maybe a 3D printed fitting to the filter?

Okay, here we are 2 months later. I have managed to find/fabricate all the parts for installation of a velocity stack and foam filter on my 026 MOFO. The V-stack is from DDM Racing ( something with RC cars ), the filter from UNI with an angle of 15 degrees, the rear cover is an original Stihl part I have modified and finally the 45 degree angle.......designed by me and a friend and 3D printed in ABS plastic. Everything fits
nicely on the 026. Have not tested the saw yet. View attachment 212309

Hello Matt,Awesome! Are you going to sell the adapter? I’d be interested if so.
YesWasn't an 044 carb used for the stack build?
