Ive googled the hell out of this and cant find the displacement of the Stihl 031 AV chainsaws. if anyone here knows, id appriciate it.

also curious about the 041, 028, and 029 models, but specifically the 031 right now.

Thanks in advance.
 
031 is 48cc
041 is 61cc-72cc depending on model
028 could be 43, 47, or I can't remember the 3rd one
029 54cc or 56.5cc depending on model

031=2.93 cu. in. or 48cc, 041=3.72 or 61cc, 028=2.62 or 43cc, 029=54c
Any model labled Super is slightly more displacement. You will not see an 031 super but an 032 is 3.1 or 51 cc
Do a search for Chainsaws collectors corner and find the website to get this kind of information.

Just curious, why do you want to know? Own or looking or what.

Wow, just realized how old this is. I doubt biggriz86 is even still active.

Stihl 031av chain saw points setting/cleaning

Hi all,

I'm new to this site and have a Stihl 031av chain saw that I just aquired and would like to know how to clean the points / timing? I have no idea how to take this chain saw apart but do have mechanical ability. Also is replacement fuel line still being made for this model? And why does the recoil make a noise when retracting?

Thanks,
Steve

I haven't read all the post, nor have I followed the links, SO, I hope I'm not repeating, repeating, repeating myself here, OR being redundant, redundant, redundant. I'm looking at something else, and this came to me via Google, as a matter of fact, this arborsite.com site and this link as well. This is another site you may want to check out:

Be kind to all you encounter.
