You won't be able to convert your existing carburetor to work with a Stihl m-tronic solenoid because those carbs have an integral fuel pump which would hinder the action of the solenoid.

Cat1 (Chris) has converted a Stihl m-tronic carb to fit a dle30 and has flown with it. I have an m-tronic carb and engine to 🫴 nvert but haven't gotten to it. Chris 3d printed parts for the conversion.

I believe it worked well but haven't done it myself yet.

Black market m-tronic carbs are all over AliExpress for black market prices.
