Build Thread - WKWS Flat top 066

[Brewz]

Hi Folks.
for reasons I'm not going to go into, I stopped posting on here for a while but I'm free of those shackles (and people) now so will start putting up some build posts for a bit of fun.

I have a really nice and vary interesting late flat top 066 transition saw on the bench at the moment for a full rebuild and porting so will keep this post updated as I go.
Covid-19 has badly slowed down parts supply here in Australia but I'm told parts ore on the way.

Its gunna be a fun build.

Stay tuned

Ok, the saw has been stripped and cleaned.
It was beautiful on the outside and filthy underneath as usual.
The saw is a late flat top with a decomp and plastic 066 badge.
It also has short cases but with the later large crank and pilot flywheel.
I have seen one other saw like this.
It also had a coil I have never seen before. A 3 screw 1128 1309 coil.
WJ 51 carb
A really nice MAHLE thick base cylinder with decomp and not the best timing I’ve seen so it is getting a 288 piston upgrade.

No Neil.... it won’t be seen in your “Arena”.... like it’s the coliseum or some f*#ken thing

found transfers open unevenly by 1 or 2 degrees. That will get fixed.

Everything cleaned
pull starter torn down, spring oiled and pulls greased.
All screw heads cleaned out.

Muffler has been cleaned up, baffle removed, New flywheel side deflector made and braised on.
Front outlet closed off bar a couple small vent holes.
I find this helps build rpm with a wide power band
In my book big front openings are bad







The owner had already opened this right up.
I'm actually thinking of closing it off some .

And thats where it stands.
Piston turned up today, using a Meteor 288 piston.
Parts to rebuild it will be a week or so. will probably start some porting on the weekend.

Great to see you back posting, but I have a question for you. That baffle looks different than any I have seen before, is it factory or was it modified?

The ones here mostly have holes in the sides and bottom but not in the front.

On ported saws I remove the baffle, but on stock cylinders I have found they often run better with just a 1/2" hole drilled through the front of the baffle, which seems a lot like what you have there.

I appreciate your comments on the muffler mods, I think too many people just think more is always better, but in my experience that does not seem to be the case. IMO, some saws loose torque with too much muffler mod, and others stop gaining power and just burn more fuel and get louder.

But there seems to be no "universal" answer, and I think a lot depends on the porting.

Yes it had been modified by the saw owner to get it breathing better.
And yes, totally agree that muffler mods need to be matched to the saws porting with consideration made to intended use for general work, racing or a mix of the 2.

I don’t like big openings at the front of the can any more. Not in our hardwood where wider power band is needed.

I just learned something. Fascinating. Thank you for posting this.

Subbed. Good thread Tony.

I really like short case poly flywheel 066. I feel they run the best out of all the 066/660 saws. Even with a 660 jug

 

[XP_Slinger]

I haven’t run an 066 in years, don’t even recall what it felt like. Next GTG I get to I need to get my hands on a couple.

 

[RI Chevy]

I'll hook you up Josh.
Nice Tony!!!

Thought Id come back and teach some of you blokes a swear word or 2

I’ll be passing by on the 90 next week, want me to drop one off?

I have 2 of them here. The other is a longer term build into a piped race saw.
