This is 62.5 ounces of gas to the same 2.5 ounces of oil, or 123 to 5 would
be the same.

The 50:1 has more gas by double.
You can make this easier ...
Add 25 quarts of gas to 1 quart of oil to have a 25:1 ratio, or add 50
quarts of gas to 1 quart of oil to have a 50:1 ratio.

Re: Newbie Questions
A 50:1 mixture is 50 parts of gas for each part of oil. A 25:1 mixture is 25
parts of gas for each part of oil. Given the same amount of oil, there is
twice as much gas in the 50:1 mixture. Or, given the same amount of gas,
there is less oil in the 50:1 mixture.
The discussion is about gear ratios, and the gas mixture was thrown in to
illustrate gearing questions. I only pointed out that the fuel mixture
analogy is flawed when used to illustrate gearing issues.
Gears are a lower when the numbers used to express them are numerically
higher, gas is "thinner" when the oil/fuel mixture numbers go up.

And I only pointed out your misstatement. Regardless of the earlier
discussion, 50:1 is richer than 25:1.

Re: Newbie Questions (going OT)
I think we all know how to mix fuel for our chain saw now. I probably used
a bad analogy. Back to the original point...
The higher the ratio (between ring gear and pinion teeth), the lower the
gear.
Or:
http://www.csgnetwork.com/rnggrpinioncalc.html
"The higher the ratio, the greater the pulling power but lower speed for the
same number of engine revolutions."
We can move on and agree, or agree to disagree. :-)
