    Visual difference between Farmertec and Stihl trigger parts

    So I have been tinkering with the idea of taking a BB'ed 066 with popup piston and doing some more interesting modding. 1. An 070, 090 carb for saws 105cc+ 2. A reed box and custom intake (No blow back and better fuel air mix with more pressure through the transfers) 3. Opening up the ports...

    Sorry for stupid long title, I wanted something that would come up in a search easily. My first 1122 series saw landed in my lap and as you guys have just had a good play with Chinese 660 copies I thought it might be a good time to start a thread. Dotted in dozens of different threads is...

    FOUND IT MS660 Handle

    I am in need of 2 MS660 handles. Prefer them to be OEM, don't have to be in perfect shape. Scrapes and marks are fine.
