Stihl MS661 C-M first impressions

[CapitaineHaddoc]

That's a great post!

I have a question, where did you get your SugiHara bar? I live in France, near the German border, and these bars are unavailables except in import.

Good thread. It will be interesting to see the gains that can be made on a 661 from porting. From what I've heard with the way the 661's transfers are designed it may not be as easy as people think an you'll be porting the case as well as the cylinder.
Good old 390's, gotta love 'em...

'Chainsawbars' in the UK should have a shipment in next week.

Love it! Thanks for posting. Keep up us updated on how the 661 does after more use. That 390 looks like fun.

Sorry guys....

Linkbucks strikes back.... :bang:

I wanted to post new photos and answer a few questions, but this is not very great with the smartphone...

I hope it works again later

Thank you for the nice welcome here! AS is just great!

Thank you, this site looks to me very interesting, even if the chains are very expensive, the guides are at good prices!

Stephan- you can run Mozilla Firefox with the "NoScript" add-on and it will work on the forum even with Linkbucks, you just set NoScript to block Linkbucks.

On the 661 air filter- you'd most likely have good results with a pre-filter like the felt wrap that come on the TS-760 filter or an "Outerwears" brand wrap.

That is one "Wicked" 390 for sure! The builders here would love to get their hands on a 661 C-M and properly port her.
Then maybe you could make a follow up video comparing ported "Apple's to Apple's"
Great post!

Your english is a LOT better than my german & considerably better than many who speak it as their only tongue! Thanks for the very professionally done vids. Though I'll not likely own another saw in the 90cc category, I sure (bad english!! I should have said surely) enjoyed watching them & hope you post more. WELCOME!

I have something new for you


I have looked at the machine more closely..

Gilardoni cylinder like the 441

After that I weighed the machines with max. fuel and chainoil

8,3kg = 18,4lb's

With bar and chain, 22lb's

390, 8,9kg = 19,6lb's

With bar and chain, 10,5kg = 23,8lb's

Today, i have cut some wood with the 661 and i must say the saw handles great! The stihl is good balanced but a litte bit wider than the husky, the 390 turns slightly better at the front handlebar. But the AV system is a dream on the Stihl, noticeably better than on the husky!
What also really excites me is the perfect production quality of the 661, everything feels high-quality and precise.

@Jacob J.
Thanks for the info

@Haddoc
I have that sugibar from a dealer on our german forum. Unhappily, the sugi's are sold out at the moment.


I hope the pictures are useful for you, tomorrow I'll take the 661 with to the woods for the first time. Im looking forward to it

I give you props for tearing it down just to show everyone. That cylinder looks really good from what I see. I wonder what our builders think... That 390 absolutely shreds! Nice saws! If you have a compression tester can you find out the compression on the 661?

Thanks!
