Love the white 105!

The 100 is tiny.

 

[Simondo]

The Ps-6100...stock.
With a clutch drum free of oil and dirt... I have never had any abnormal slipping while testing them with bars up to 20" and 3/8 chain in hardwood.
Even with a saw that has been used for a while ..still no slippage.

 

[Simondo]

A little more info for all ....The 6100 has a higher than most clutch engagement RPM . Many 60cc class saws have 3600 rpm as there engagement number.

For the purpose of the picture a tangerine 105 might have suited better, but unfortunately, I don't own one

I tend to agree with your statement. My 6100 will slip the clutch when it's pulling hard. I'm not talking about lugging the motor either, just running it with a fresh chain and a bar full of ash tree.
Has anyone else experienced the same thing with a 6100? Mine is all stock by the way, 20" 3/8's

I'm going to keep an eye out for it now.

That's a lot a bit high. What are the engagement speeds for other saws using the same clutch? Just wondering if different springs are used.

PS-420 has exactly the same numbers

 

[Simondo]

Clutch engagement RPM as per Manuals...
Ps-32 and 35 =4100 rpm (different clutch )

Ps-420/421 = 5100 rpm
Ps-5105 =3900 rpm
Ps-6100 = 5100 rpm

This is the only Dolmar model with white dyed plastic parts. These usually turn yellowish over the decades, mine as well but fortunately not too bad. The saw looks better in the pictures than in reality, however IMHO it is a very pretty saw.

That is a Sharp looking saw! Very nice!

I put a Tac on a stock/clean /low hr Ps-5105 today, just by way of interest over the factory clutch engagement rpm.
It just about starts at 5100 rpm with a normal tensioned and oiled 15" .325 bar and chain. No engagement at all at the 3900 rpm the manual shows.
Seems the clutch on the 420-5105 and the 6100 being the same ...has the same engagement, not 3900 rpm after all.

Interesting find. I could see where a higher engagement would not be detrimental to a smaller saw, whereas the bigger 6100 would not be so critical as to the engagement speed.

By the way, my 6100 only has around 10 tanks of fuel through it, so it's doubtful the clutch drum would have dirt or oil on it. It's the only saw I have that I can actually hear it groan when it slips in a cut. And I believe in letting the saw run without "dogging in" to make it cut. I will take it out soon and give it another go with a tach too.

The Dolmar clutch drums can easily be taken off and cleaned, as such there is no excuse not to do so occasionally.

Oil always finds it's way into the drum, after 10 tanks of fuel the drums friction surface will definitely be oily.

I clean the drums on my Dolmar's with a dry cotton cloth whenever I remove the clutch cover on any of them - unless I didn't run them, in which case it'd be a futile exercise.

 

[Fishnuts2]

I'll tear it apart and clean it before I take it out!

If any of you guys can help me find a handle brace like this for a CT, please PM me.
Thx!

Lovely!
I have a nostalgic thing for the 105.

What kind of sharpener was that in the 6400 video?

 

[RI Chevy]

MMWS 6100 looks faster and stronger than 6400.

Even with regular work chain I bet it's faster.
