661 was definitely faster.

 

[jmssaws]

Is that the same 394 you just sold?

Yeh.
It's tuned at 13k
I tried it at 13.5 and it kept running out of gas in that long cut.

 

[jmssaws]

The 661 should adjust for timing and fuel depending on rpm and load. So it should feel like it has a wide power band. Is that how it feels when you push on it some? You got the airfilter cover modded on the lower right?

The 661 is exactly how it came from the factory,all it has done to it is a bunch of grinding here and there in the cylinder.

That is the sickest 661 I've ever heard. Wish mine ran like that!

 

[Wolverine]

but I thunk the 661 was stronger, I thunk.

I was saying I believe the coil module changes perimeters based on the rpm and load its under in the cut

 

[jmssaws]

I believe that the 661 is stronger but not by as much as it looks,the 394 is tuned 500 rpm to slow but it's the only way I could keep fuel to it in a minute long cut.
Tuned any faster than 13k it will start running out half way through.

I was saying that the airfilter cover is stock. Lol

500 rpm to slow and a half turn farther out on the low than it needs to be and still is hungry at the end of that cut.

What can you do other than a larger carb? Would raising the metering needle any help

 

[jmssaws]

I've had to gut the fuel filter before on them.
At 13.8k with that bar and chain about 20 seconds is all it will do until it runs out of fuel,let off a split second and it's ready to go again.

 

[Chainsaw Jim]

I was going to say...if it is it isn't tuned like it was. It seemed like it come out of the cut a little skinny.

Why would a Saw tuned leaner run out of fuel faster than a Saw tuned richer?

Could the compression of your 394 be causing it to lean out with long cuts?

 

[Chainsaw Jim]

Those white Husqvarna filters are less restricted than you think. Fill a measuring jar up with the amount of fuel equaling a fuel tank. Then suck it out with a filter connected to a fuel line. It shouldn't take longer than a few minutes. Ain't no saw trying to suck a tank dry that fast.
Be careful hogging out or gutting fuel filters because part of their design with the foam or density is to eliminate air bubbles traveling up the fuel line. That can roach a top end if you're milling or running hard.

I would think it's something else unless the filter is going bad.
Usually the carb needs more fuel flow when everything else is dramatically increased.

 

[RI Chevy]

Maybe put a bigger jet in the carb?

I was thinking the same thing Doc

just got this back from Dr's office.

Real nice! Runs strong, idles well. Cuts well. Great worksaw. Another MOFO Worksaw!
I saw you with what looked to be a tach. What were the RPM'S?

14k, idling a little under 3k. Perfect!!

That ash log was stone dead last summer when that tree was cut. Rock hard and frozen.
