Just for fun I've been working on the 2375 Wild thing to see what I can get out of it. Had a couple of burned up examples given to me, both complete for the most part.
Ordered a new piston/cylinder kit off of Amazon and was pleasantly surprised to see that it is a proper chromed unit with no voids or pits.
The new cylinder has a slightly smaller and more oval shaped intake port, the transfers are very slightly larger from what I can see, and the exhaust is considerably larger at the opening by the piston with much less taper than the stock one. The top of the exhaust port also has a small step in it, perhaps to prevent too much blowdown.
A muffler mod was also done, the horrible stock muffler was taking apart, gutted, and brazed back up. The fold over seam is ground down until you can see the edges of both halves, and after the muffler's pulled apart everything pops out.
Half of the muffler has the flange bent over slightly to give more fill area for the braze. Worked like a charm, very little flowed over.
The stock tubes that reinforce the muffler were cut open with a grinder as you can see. The total area of the cuts are slightly larger then the frontal area of the tube. They simply slide back into the muffler and get bolted up as they were before. The old exhaust exit gets filled, and the stock screw holes get plugged with the screws. Very straightforward mod if you have the required tools.
One word of caution if you are going to do the muffler mod. The mufflers are aluminized and the flange edges must be dipped in muriatic acid to remove the aluminum for proper adhesion of the braze. Do this outside, you'll get some nasty fumes off of it.
This will work on the 2375 wild thing and several other non-strato saws with this type of setup, they are pretty easy to work on and the piston and cylinder kit was cheap.

she'll be a whole different saw. bigger carb/intake too
