Use pipe and sonic waveso how does one make power out of fuel lost out of the muffler?

it's a split carb system, so there's nothing to disconnect.
That’s the 64000 questionI have two of them
I know how the work
Just was thinking it lets fresh air in one it and might want run leaner then all the air running through the fuel side

When you delete the strato do you unhook the fresh air butterfly or what?

You must be thinking of a 441. There's no fresh air butterfly on this saw. It has a single venturi carb.

I agree ... perhaps at high-rpm a bit more fuel is combustible and that’s where Mr Snelling is finding his gains ... but alas what you gain here ya lose there - simple physics 101the strato ports were added to 2strokes to purge the exhaust gas from the cylinder before the fresh charge enters the cylinder. it seems to me that gutting the stratos is just pumping fuel out the muffler. if i'm wrong, please explain
just the tip? I was hoping for the whole thing.
??? Hello hello anybody out there !where's the after video?
anything for you scotty.

maybe not cause it to be lean, but lets look at at it.

most of the venturi has been removed from the lower part of the carb, this should increase air flow. by gutting the strato one would think that there would be less flow through the top half of the carb. I believe this is true. less air flow means less pressure drop and less fuel delivered. so now to compensate it needs to be richened. no problem, however with lower air speed in the card the fuel won't atomize as well. this can cause some poor performance issues.
Fresh air
No fuel

once the stratos are gutted there is no fresh air. that's my point
