Mastermind Meets The Dolmar 7900

[mdavlee]

I've got dolkita all over my work bench. At least the 6421 turning into a 7910 has a muffler mod and slr gutted already.

 

[Mastermind]

What I find interesting on the 7900 is the shape of the crankcase at the transfer opening where it meets the cylinder. That looks like some "black magic" to me, and could be a detrimental to the how the saw performs.

Hello Joey.

I've got a full plate these next few days. But as soon as I can I'll get a video of the 665/7910 for you guys.

 

[Mastermind]

This is great guys. I've had no desire to talk saws in months. No I don't have time.......its still a great feeling to want to again.

It seemed like the solo thread kinda died on the vine

Carl is here. And this is what's exactly on my bench and 3 solos 665 conversion are on there way. Hi Randy! Excuse the messy bench. Lol.

And actually I fibbed a little the right one is done. That's the one I have for sale that's been to Jeremys, Nates, and Matts gtg. It's at 102/130/80 but has an epoxied intake to bring it back up to 80° as its running a tad more comp than normal.

 

[Miller Mod Saws]

This saw has the same numbers as the one I just did Mike.

Thats look awesome my man. Does the low intake bother you? If you brought her back up to the 80 range do you think it would help?

 

[Mastermind]

I'm cool with 82 or so on it Carl.

Glad you are here. Jump in with a build thread bro.

I can't believe you have not sold that saw yet Carl.
It's a great running saw.

 

[Mastermind]

Yes it is

I drove it in KY, and was very impressed.

1 of the 3 445. This one bad big end.

Raised intake to 78 From 86 or 87.

Whapping off the limiter..
That's what you were looking for!
Now for those blasted coils... 16,000 rpm is right around the corner..

We're back where we were at least. It's not slower than it was 3 days ago now Now if our good ole buddy that owns this forum could get that boat turboed or something

Dang VP fuel. I'm out of pump gas. I ran out on the maple cant on the 2nd cut. I finished it off and figured I'd try it in the oak. Crappy chain on it as well. Stock LGX. Need to touch it up with a double bevel.
