Put an 8 pin rim on it and you'll be even more impressed for most cutting.

I wonder if anyone with a 440 or 660 huztl is near a small engine dyno to see what the hp and torque looks like?

That's the most common reaction. Sure you can feel a difference between OEM and Aftermarket, but for most of us the price difference more than makes up for it's faults.
Good job on the build
Thanks! Wish I knew someone with an OEM 660 to compare it to. I'm sure the results would continue to impress me.
Why do you say that? Im not doubting you or anything...just thought the 9 Pin on a 20" bar was the "magic" setup.
Agreed. Thought you had standard 7 pin rim.Thanks! Wish I knew someone with an OEM 660 to compare it to. I'm sure the results would continue to impress me.

I do at the moment...the 9 Pin is on it's way still.
In small to medium softwood, it is difficult to slow the saw down with an 8 pin. Where are you getting the 9 pin from? I would like to try one.
If you're asking why I'm using a 660 on small to medium softwood you just don't get it!
IMHO, a 9-pin rim has no business on a 600. In wood of any size, a 7-pin will work best.

Oh trust me, I get it! It's a Danzco Performance 9 Pin Rim, and it is coming from "dssjms" on eBay. I believe that's "Definitive Dave" on here (?)
I trust that you know what you are talking about. But...why do you think this?
From trying it and watching others try it over the years.
The chain speed for an 8 pin is 14% faster than a 7 pin and a 9 pin is 29% faster (assuming the same RPM). It just shows chain speed is not the only factor.
It takes a lot more torque to turn it. Only the strongest of ported 90cc saws will be faster in the cut with a 36" bar cutting proper size wood.

Brad, Probably good advice for a work saw but I see nothing wrong with saw builders / tinkerers playing around with pin #s...especially with shorter bars and soft woods. Isn't this part of how race saws came about. I thought I read many reports of good results with 8 pins and moderate bars on 90 class saws with recommendations to return to 7 for felling & bucking with longer bars.
Did you get a chance to give her a spin?

Just got my .74 Jet in the mail today. I do believe I have the A/M Carb that is the replaceable jet style. Do you find it made a difference? I was thinking as "wild" as I built mine, I'd need it. But at the same time, my carb honestly didnt seem to be lacking in keeping up with fuel flow. While breaking in, I could add enough fuel on top to keep it limited at a safe 12k. Im starting to wonder if I'll actually gain anything.
On the last one I did with mild porting and port matching the baffle less muffler. I was almost 2 turns out with the .64 jet. I like my adjustment to stay 3/4 to no more than 1 1/2 but that's just me.
