Lol. I had one. I liked it. I just can't tune those Dolkitas. With that said, I do have a nice Dolkita 9010.

That's terrible to keep such a saw alone away from it's family. Send it my way and it can look over and spread it's wisdom amongst my village of smaller dolkitas!

Here you go @RI Chevy .

I took the rakers down, maybe a bit too much for the 8 pin.

Nice! Much better for that saw. Wood looks like marble.

It was pretty hard for sure being frozen, but previously dead standing locust is harder . There surely isn't going to be many big chips. That chain was a fresh square ground work chain.

And so it goes, another disappears down the blue worm hole.

 

[Red97]

Boom... + 15cc just like that.

I think these are technically designed to be 73cc.

64cc is under bore, 79cc is big bore.

I like my 73cc's very much.

Good looking smurfette!
My favorite spikes on her too.

Did you advance the timing? They like a little bit, but too much and they pop. Nice results though Joe. Nice wide powerband.

No, I didn't advance timing on it.

What's the general feeling on the HD filter set-up for the 79xx's boys? A quick search seemed to indicate that they were flow restrictive? My (ported) saw has a white filter under a shiny black oe 'low' cover at present.

Waste of money and restrict flow.

Wow. Gold plated insides???

Hey Mason you forgot the IMO part...

While tests have been done that do prove the restricted air flow with the stock filter the HD cover gives you space to make it worth it.

It’s not an opinion it’s a proven fact as you stated. The HD filter “neck” is mostly the problem. Some have made custom velocity stacks with aftermarket filter options that make the HD setup work better for them.
