Yes. 25 parts of gas per each part of oil as opposed to 50 parts of gas per
each part of oil.

Actually, the number is 125, not 125.5

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. :-)
