You can try the .040". Mine didn't pop with .035" off. Every saw is going to be a little different. I'm just filing them.

Got the correct parts to do the complete euro conversion. Cut some cookies to check tune after it is warm seems to do pretty good. I will use it next week to cut timber.

 To go to adjustable carb etc


Want rid of the Mtronic on your Stihl 661? We have 2 complete sets of OEM 661 Euro parts. Bolt on some reliability with a standard adjustable carb and matching ignition coil with all small pieces to do the job right. $325 each shipped.
picture doesnt show it but there is also the grommet for around the carb adjusting screws
