--"swthollitoes" gave a good answer. When he mentioned "expansion chamber" he was talking about the exhaust pipe. Between the engine and the silencer (muffler), a 2 stroke has a bulge in it about 6-8" in diameter.
--When he mentioned valve head - look at the cylinder. Near the top of the cylinder, you can see where the "cylinder head" is bolted to the cylinder (you'll see the edge of the head gasket). A 2 stroke's head is about 2-3" thick. A 4 strokes head will be 4-6" thick.
--Some 4 stroke models have a "valve cover". And some have inspection caps on the head, in the front & rear. They're removable to adjust the valves.
--4 stroke engines with a valve cover will look like this
from the side going from bottom up -
Engine - gasket - cylinder - gasket - head - gasket - valve cover.
--Another "tip-off" - a 2 stroke engine will have the spark plug sticking straight up, in the center of the cylinder head.

to look at them a 2 stroke has no valve head. it does not require a valve system to work. on the four stroke, you will see a valve head, and a smaller header pipe. a 2 stroke has a bigger expansion chamber that is very noticable.

also, a 2 stroke needs oil mixed into the gas. Four strokes have oil in the engine and dont need oil in the gas

IT ALL IS IN THE STROKES IN THE PISTONS WERE A 2 STROKE HAS INTAKE COMPRESSION, ON ONE STROKE OF IT AND EXPANSION EXHAUST ON THE OTHER == 2 STROKES 4 HAS ALL OF THEM 4 STROKES OF THE PISTON TO COMPLETE A FULL CYCLE INTAKE . COMPRESSION , EXPANSION, EXHAUST THAT IS WHY A 2STR REVS HIGHER TO COMPUSATE FOR THE MORE CYCLES IT HAS TO GO THROUGH

2 stroke - intake , exhaust done thats it
4 stroke- intake , compression, power, exhaust . simply more efficient which is y its used on cars now!

I can't tell the difference by looking at them, but they sound distinctly different. A two stroke has a much higher pitch(like the cycles you see on x games that flip). A four stroke sounds much lower in pitch(like a four wheeler).
