Damn! It looks like you're a bigger stroker than I am.

Re: Engine quiz
21/30, and surprised I did that well.
But then what do I know about engines? I'm a bicyclist.

Yes, I suppose I could agree with you ... but then we'd both be wrong, wouldn't we?

I had some lucky guesses too.
In my defense, the only two stroke engines I've ever owned are my Stihl chain and it's brother, a concrete cutting saw.
How should anyone know who invented or perfected the two stroke or when?
What the heck is asymmetrical cylinder timing?
It would seem to me that 50:1 is closer to 2 ounces per gallon than their 4 ounces per gallon answer. (Actually 2.56) I'll have to look at the tiny little bottle that came with my chainsaw. I kept it to measure the 2-cycle oil I buy in quart bottles.
How can oil, which is mixed 50:1 in the crankcase, be said to originate in the carburetor? Heck, it originates from some old dead dinosaur if not the crankcase or, in some cases a separate oil tank. I answered neither, and still think I'm right.

Re: Engine quiz
I got 23 out of 30, several wrong guesses. And I agree with MGM- the oil doesn't originate in the carburetor. It originates in the fuel tank, and is often blended before it even gets there.

Re: Engine quiz
Some 2-cycle powered devices carry separate oil and gas tanks with separate feed lines to the carb. I did find it interesting that big ships (which use something very similar to road asphalt for fuel) are 2 cycle. Reminds me that the compression-ignition engine was first intended to run on powdered moss or coal dust, which meant very short bearing life. Modern metallurgy has made all kinds of weirdness commonplace.

Re: Engine quiz
As far as oil originating in the carb, I think they meant where does the lubricating oil come from into the engine. There is no oil pan so the oil to lube the crank/connecting rod comes from the carburator.
As for assymetrical timing, it has to do with the porting (of fuel/exhaust in and out of the cyclinder).
Here is a lengthy and a bit confusing explanation.
