This vid explains the 2 stroke pretty well. I want a saab 96 2 stroke
With a 2 stroke you get good power to weight so you can have a pretty small engine with good power. Need to mix oil in with the fuel aswell.

What is the difference between a 4 stroke and a 2 stroke engine and what is the "stroke"?

4 strokes have cam shafts and valves, 2 strokes do not.
They are much simpler, but don't bother with anything 2 stroke as the EEC are banning them very soon.

That's not entirely true, most of the 2 strokes don't have camshafts and valves, but there are with valves.

2 strokes go 'ring ting ting' and stink.
4 strokes go 'brum brum' and sound crap against a 2 stroke with a 'spanny on
3 moving parts in a 2 stroke, thousands in a 4 stroke.

You can't beat a good two-stroke (I've had sooooooo many! ).
Did you know, the last of the Honda NSR500 grand prix bikes had been known to put out over 200bhp! They never raced them though as the wouldn't
last a full race....
Yes, that's 500cc, normally aspirated, 200bhp!!!
In mc racing if they have a combined field with 2 and 4 stroke engines, almost always the 4 strokes may have about twice the dicplacement against the
2 stroke.
remember that a 2 stroke makes twice the powerpulses per revolution compared to a 4 stroke.
dragracing also used 2 stroke engines with rotating-disk intake and superchargers, those thing made power beyond believe per displacement.
