This may have been posted here before but I happened across it and wanted to share it. It's a cutaway of a jonsered chainsaw, it really lets you see what's going on inside one. I thought it was cool.

Went to an auction once where that was done to a Ford 8N tractor. A buddy of mine bid it to over $4,000 but did not get it.

Wow! I see those go for less than that running sometimes. All depends on who is there.

What's with the metal hoses coming out the front top

Interesting. Looks pretty old to have a chain brake. Neat pic!
That thing won't run very well without a piston ring, flywheel, ignition, ... 
Just pointing it out!
Is that a definition of open port now?

I have a part of an unknown brand 2-cycle engine cutaway I bought at an auction. I'll try to get a pic of it soon. Not nearly as cool as the Jonsered though. Anyone know it's model? Kind of resembles a 49SP but I don't think it is one. Air filter is different.

I had to google and found a couple more.
this looks like maybe a husky?
this one is a 2 cylinder, interesting. Who would have made a 2 cylinder 2 cycle saw? I've never seen one myself. Anyone else here on AS have one or seen one run?

Echo made a twin.

I've seen the John Deere version of the Echo twin back in the 1990s. I've wanted one of them ever since. They were hard to get parts for (as I recall).

The full cut away saw is very cool, but much more complex! Do you show the flywheel or the clutch? Some things are only on one side.
Here is a cheap Homelite that I sectioned after seeing the one @Chris-PA showed. It seems to lack compression, but it is missing the ring . . .

PS - I believe that Solo also made a 2 cylinder chainsaw.

Was that a 46cc saw? When I see that cutaway it makes me want to see what I can get out of one of those. Except for that con rod that is - that reminds me of the Stihl design. Nonetheless if the rod holds together I bet it could be made to run pretty well.

The John Deere and Echo twins were opposed. One cylinder to the front and the other to the back. Horizontal cylinders

Here is my dirty and crude version I bought at an auction. Definitely was a crude job.

The cutaways you guys made are cool as well. I've always like cutaway engines and such. Really gives a good look inside while the parts are in place and in motion as well.
