Marcel Vincent MVP ported 166 on muffler and 11T.

Carb set real rich on wot tune and showing how they clear up in the cut.

Same saw on tuned pipe after a fresh rebuild after hanging a ring early in the year.

At the start of the video it sounds like you are starting and blipping the throttle on an old dirt bike.
-
They do sound different even at idle.

-
in your opinion. which of the big three is the strongest? [084,166, 3120]
-
All stock and no limiters of any kind (coil or carbs). I would take a 084.
I ripped with the 084 and 3120. Never ripped cut with the 166. But IMO it wasnt close to the 3120 and 084 in the cuts.
Now you start putting 72" 84" bars and redwood trees that long stroke might come in to play on the 166.
-
Here is the video I was telling someone about ;). Sound of a 166 idling.
Leeha has a video of 12-14 of them idling together. Sounds like a top fuel car. IMO ;D

To the guy asking about replacement dolmar 166 piston.
Lee H. leeha ( I have email and # if needed and he ok's) had these Dolmar 166 Wiseco pistons made up for stock replacement and they were lighter then stock with wider shirts and 1mm rings. I had bought 2 from him for around $155 apiece shipped

2 more pics of actual 166 piston I had in hand.
-
Pistons do not come any nicer than that
-
That big old hoss had the power I'll have to say .
-
I'll have to agree.
That piston is a work of art!
Is that 166 stock or did you help it out a little?
Mike
-
Mike that one in video on muffler was tweaked by a Canadian ole timer racer to be run in stock saw classes.
Now the alky nitro 166 was the one that impressed me. That was the one I bought those 2 wiseco pistons for.
-
I'd agree in stock form I'd take an 084 over the big sachs .However that piped one would rip now .
Then again big azzed saw like that no matter who made if used in huge wood there probabley wouldn't be much difference at the end of day .They'd all saw a lot of wood and you'd plume be tuckered out .
In these parts though those monster trees are few and far between .You might stumble on to only a few in a years time maybe in several years time .
Bad thing is on a large saw most times unless you fire them up occasionally they've sat so long you have to wrench them every time before you use them .Now this I know to be fact ,trust me .
-
I know where a Sachs Dolmar 166 is for $900 if somebody want me to dig deeper into and get pics etc.
-
There was talk and conjecture of mating a 166 lower end with an 090 P and C because to date the 166 had the longest stroke of any saw ever produced .However with a means at hand to use a Huskey stroked crank with an 084 rod and a special piston I think that thought pattern went by the wayside .That is getting into to territory which is way above my pay grade and my pocketbook for that matter .
-
Friend of mines latest find. Dolmar 166
-
That doesn't look like it has had much use. Nice.
-
The 2 dolmar 166 runners I had in the video's above.
-
Found a video of my sachs dolmar 166 making 3 cuts at a gtg on muffler. Not very fast on muffler but had to try it.

I am pretty frustrated with my 166 right now. So frustrated to the point that I have it hidden in my shop so I don't even have to look at it. I think I would love it if I could get it to run right, but I have done all I know to do to try to fix it besides buy a new carburetor and nothing has worked.
-
cowroy, JMO 166's are for selling or as collectors IMO. Not for working, running cutting with.
-
I totally agree man! I am on the verge of this one going away and since I am here where there is a little less traffic and more practicality, I don't mind saying that. i just haven't made up my mind yet. I would just like for it to run where I could make a good judgement ::)
-
Send it up here Justin and I'll give it a whirl

Do I know you? ??? Obviously I do somehow, but the screen name don't ring any bells. :)

LMAO he was just plain mean for doing that to ya........ ;)
-
Yeah I forgot what account I was using when I posted.
-
LOL, now it makes sense!
-
Like I said before I ran Kevins souped 166 at Chardon and had the stocker for a week or so to practice with .It was one powerfull machine but it wasn't as good as an 084 as far as user friendly .
I kind of put them in the same class as my 125 McCullochs ,Damned fine old saws but getting to the point it's nearly impossible to find repair parts for them .Those things were made to run giant long bars in old growth PNW stuiff which they can still do .Just how many 6-8-10 foot diameter trees does the average guy run into ?
-
I agree Al
-
Been looking for a new air filter for my 166 for some time now with no luck, so lashed up this cone filter and inlet manifold, not pretty but makes a hell of a difference to performance. Patrick
-
I like! Looks good to me. I have several V-stacks just never used em guess I'll have hook one up.
Shep
-
Cool on the v stack build. I had new NOS filters but let them go when I got out of the 166 stuff. If I come across the filters again I will let you know.
Oh question, did you have the flat 2 piece air filter that fit under cover or did you have the K&N set up V stack ones with cut out AF cover. Those were both used on the 166.
-
I see your AF cover now for flat filters. You can get a modified cylinder cover and af cover just for the style you went to. ( I had them but no longer have that either). Sorry.
-
Was the cylinder cover all one piece with the air filter pipe?
-
Going to say no, but memory is sketchy now, been awhile. It was just cut out and modified for the K&n. Ill try and find some pics. I know I dont have the cover I had or pics anymore.
-
Can you see these pics?

-
I'm thinking the air filter cover was tack welded and cut out to the cylinder cover too. On the k&n ones.
-
yep, can see those picks thanks, think there are a few NWF filter heads there.
-
Guess I need to save these here too.
Race ported sachs dolmar 166 compared to a work ported 166 exhaust.

Man that exhaust port was raised quite a bit on the race saw.
-
Missing a pair of oversized epoxied transfer covers. ;)

No it wasnt. ;)

That is a huge exhaust port.
-

No it wasnt. ;)
Not worth a try along with a kart WB carb or something? :D

External boost ports and oem piston ran backwards.
Marcel Vincent Performance MVP Canada, I think he knows what he is doing. ;)
Carb was a modified WG2. Dang thing could swallow a golf ball.
-
Yes I know that's a MVP saw. I've worked on a 084 and 090 built by him back in 1989. Exact same style of cut off head like on your 166. I couldn't see any epoxy on the transfers in your pic, as that's what Marcel did to the 084 and 090.
That's why I commented "the epoxied covers are missing". ;)
-
Have a thread here on this fix I did 6 or 7 years ago.
Only one way to stop the bar oil from ruining that $30 a gallon alky/nitro sprint nitrodine fuel = 2010 price. Split that metal tank and sealed it back with Threebond 1194.

Great thread! I recently picked up a 166 from a member. One of the last Holy Grail saws on my list. Now if I can just score a Jonsered 111!
Scott
-
Some old pics of mine. The one is Lee's stock exhaust port. My old woods ported one and race ported one. Just some comparison pics from way back.
-
nice !
Can anyone sell or recommend me a piston pin ?
I just had one machined by a workshop specialized in repairs of old engines.
Made good experiences with those guys in the past. This time, however,
they charged me quite a bit and I do not like the results.
Poor appearance and heavier than the original. They also messed up
the original (yet a bit corroded) part I sent them as a sample.
well, this was stupid....
-
Maybe these will work. 166 piston kit. https://www.ebay.com/itm/Sachs-Dolmar-166-piston-NEW-chainsaw-/371701882056?_ul=IL
I know my backups were 166 wiseco pistons with wrist pins.
-
If u're ver gonna sell one of these wiseco, pls gimme a note !
No kidding, I also got one of the fameous sprocket covers for 090G that were sandacsted in Australia, I know what it means to be patient ;-)
actually, I do have one of those piston kits here. However, I will try to avoid parts of unkown quality.
If I cannot find sth. else, I will use the pin I just got from the machine shop. At least it is made of steel 16MnCr5, just wish it would not be heavier than the Original.
Best Chris
