Ms170 bucket saw need help

[Chev727]

Bought a ms170 in a pail completely torn apart, I've got it semi rebuilt and about 90% together but don't know where these parts go or how they go on

Top one is in the brake parts

 

[HarleyT]

2nd one goes under the carb

 

[HarleyT]

3rd one is also on the brake parts

 

[HarleyT]

4th one goes under the coil.

The round plastic ring goes behind the carb. The piece below is part of the chain brake. You need either an IPL and/or a service manual.

Thanks for the help guys, bit of a headache when you've never touched one of these before, slowly getting there though, trying to find where the yellow/green wire that comes from the coil goes to now, wish i knew where to find a free manual online

 

[HarleyT]

Here is the manual.

Here is the coil, the wire/spring goes into the housing under the black throttle control, making the circuit for the kill switch.

Here is a pic online of a Stihl kill switch setup, not exactly what you have, but same idea.

Thanks again, seems I'm missing that spring for the shut off, managed to figure out the brake though

 

[HarleyT]

I dug out some parts, here is where/how the spring fits.

The channels at the top hold the wires in place.
