wow impressive

You don't have to lie, just because I begged for a response, lol

 

[blsnelling]

In that size wood I'm not sure how much you can tell, as you pretty much mentioned. Seemed like it was holding rpm's better for sure, and the throttle response is there too.

Do you have any more decent size wood to cut?

I do, glad to have help

Hey, Im not going to lie, I kind of got a chub. that saw was impressive response

 

[LowVolt]

I would like to see a ported one ran next to one with stage 1 mods.

 

[crabby cooter]

cool brad, how did you determine what port numbers to use?

 

[redbull660]

It's just a short three cut video, but it's all I can give you for now. As before, cut times are very inconsistent due to the wood changing size, a big knot in the wood, and purposefully varying the load in order to demonstrate the powerband. Never the less, I'm guessing that I have maybe a 20%-25% going over muffler mod and timing advance. The saw runs perfectly with WAY more lugging power than stock.

sounds good brad. got all the times from first video posted and the one just posted (after porting) if anyone cares...

stock saw cut #1 - 13.1 (guessing this is the natural grip/pressure cut)
stock saw cut #2 dogged in - 12.8
stock saw cut #3 - 15.0 (appears brad is letting it self feed?)

muffler mod #1 - 15.3
muffler mod #2 dogged in - 13.0
muffler mod #3 - 14.1

Timing advanced #1 - 15.7
Timing advanced #2 dogged in - 13.3
Timing advanced #3 - 15.6


Ported #1 - 12.3
Ported #2 - 10.3
Ported #2 dogged in - 11.7
Ported #3 - 11.6

Yah , that’s similar to what I came up with + or - a hair

 

[crabby cooter]

so that's a 2.5 second gain?

 

[crabby cooter]

why was the same chain not used?

 

[Frank Rizzo]

That’s a C.C. 2.5 sec lol ... from the test results it’s seems the ported Saw ( squish,mm,+8adv ) was quickest , 2) stock saw , 3) mm , 4) mm +8adv timing ... puzzling results in same wood with same chain ?????

Wood be interesting if Brad wood show close-up of spark plug ...

So if you cut a tree into 20 rounds you can save a minute.

I was going to average the fastest time with the dogged-in time for each of the runs, but for the first 3, the dogged-in time is the fastest time, and for the port job, it is one of the slower times.


Dogged-in times might be the only solid apples to apples comparison in the bunch, which was 12.8 stock, 13 with the muffler mod, 13.3 with the advance, and 11.7 ported.

Do you have any more decent size wood to cut?

I'm sure we can find something.

 

[blsnelling]

Guys, you're wasting your time trying to do a straight up comparison on the cut times. Did you not see how much bigger the wood got and the hug knot, we cut into after the stock cuts? This was anything but a measurable scientific test. I'm simply showing you how the saw runs in the wood that I have. You're going to have to use your ears, not the stopwatch.

 

[blsnelling]

why was the same chain not used?

Because the wood isn't good enough to even pretend that cut times are a straight up comparison. Also, a lot of firewood was cut with that chain since the last cuts.

 

[crabby cooter]

ok cool brad

so how do you determine if gutting the strato's helps ?

Flow-measurement ... another very simple way is to look at spark plug - perhaps Brad will show pic ..... no ?
