Tastes like old boots soaked urine...

*edit* this is a quote from one of Australia's early colonial explorer's diaries.

Yeah they taste just like cat

Interesting....I imagined more of a Vicks vapor rub flavor.

Thought this may be of interest.
I noticed some distinct differences in the lowers between these 2 cylinders.
One is a Mahle 066
Other is a KS off an MS660

The KS has very tight lowers that are quite squared off with little port towards the intake



The Mahle is more open with more open port towards the intake.



They both run great.
I have been running the KS lately and it goes like stink.

Interesting

No that's what vegans taste like

Compensating for case capacity on one and not the other

Which one do u like?

I've tried 100 different ways and the short case saws are always stronger.
The size of the transfers stock don't really matter to me it's the timing that matters.

KS seems alil stronger stock?

On a 066/660 no,ks is either a red light or 660 cylinder and they generally aren't very good. Mahle is the one you want.

I prefer the mahle 064 cylinder also.

Ive never noticed KS to be any better in port dressing than the Mahle but I have seen a few Gilardanos that were very nice in port dressing

If I remember right Jason the KS 1st yr 046 was the one with spot on #s? I think John still has one we built that was a very strong stock

 

[Brewz]

This one is being built on a big case bubble top 066
Its not going to be the fastest saw ever built but I have the saw and its a good saw that's been fully rebuilt.
Its got the open muffler and big K&N on a V Stack so needs a motor to take advantage of it all.

Will use the Mahle and a 288 piston after a bit of metal removal and see how it goes.
Wont be anything extreme, just a good running work saw for running 404 chain in hardwood

 

[jmssaws]

I build lots of 660's with machine work and a 288 piston only. Good work saws.

I don't use a 288 piston in ported saws anymore.

 

[Brewz]

Both of these are times about the same and not great.
If they were good I would stick with a stock 066 piston but I will need the 288 piston to get the exhaust down and keep the intake in check.

Where were the exhaust on thoso 2 cylinders stock?

Its the best option I can see for a cylinder with a high exhaust and low intake.
I dont want to port it out to make it scream and push the power up to high, I just want it to run better.
