When a 2-cycle is running to fat/rich, it has more fuel then O2 in the mixture and the flame goes out, it makes a sound like a 4-cycle engine. Often called 'burrble'

Have you ever heard a small outboard boat engine at idle? That "burble" sound from the exhaust gases coming out of the water is what 4-stroking sounds like.
Well, it does on my engine, I don't know about yours.

Sounds like the plug is going to foul.

Never had it happen, but my friends david bradley will 4-stroke sometimes.

Check out THIS PAGE. They have sound clips on there, and if you listen close, you can hear it.

EDIT: I guess their full rev clip isnt working, which is the one you can really hear it good. Anyways, I'll leave the link up because its a very good guide to tuning carbs and we always seem to have questions regarding tuning.

The difference between four stroking and two stroking is the difference between braaap and eeeeee.

With a saw, you want it to limit its own speed by four stroking at full throttle when the bar isn't in the wood.

With a 50cc scooter, four stroking at full throttle means you top out at 20 mph instead of 35 mph.

That's a good way to put it. 4 stroking, think a big v8 with open headers, and 2 stroking is alot smoother and sharper sounding.

A saw can still get that throaty sound without 4-stroking, i've only seen it on two saws they were old ones.
