ms660

Knowledgeable ones I am your student here. Purchased and assembled the Chinese clone MS660. I really enjoyed the build. I have a specific question concerning port timing and what to do to fix it. I mounted a degree wheel and the port opening measurements are as follows. Intake 95 degrees ABDC...

Visual difference between Farmertec and Stihl trigger parts. I saw a post asking about the quality of the latest kits. Well, I bought a clone MS-660 from someone on E-Bay. Towards the end of the two year square deal warranty it started to get very hard to start and run, so much so, I could only...

Anyone have a piston cage bearing for a 660? Genuine STIHL 9512-003-3281

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...

FS: Stihl 066MS660 1122 54mm cylinder "B" casting with decomp. Transfer was cleaned up but i found a few areas as seen in the pictures with pitting in the plating. I think it would make a great cylinder for a quick worksaw fix or port job experiments, or whatever else you think it can be used...

Still trying to do a 50:1 660 build, if I change to a oem sthil piston, pin, bearing, and a lower crank bearing, does anyone think that this would work for what sthil says should be a 50:1 saw. thanks

Hello everyone! I’ve acquired a MS660 and I would like to convert it over to a v-stack because I think it looks cool, I’m also going to be in the market for a 40” bar for it as well, I have plenty of saws with 36” bars so I’d like something a little bigger. Any help on this subject would be...

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...

This is the Official build thread for Stump Shot's FarmerTec MS 660 Class 3, named Little China Girl.

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.
