Not when you are talking about the richness of the mixture, you're not.

Gear ratio 3.73:1 is higher than 4.56:1
Fuel/oil Ratio 25:1 is leaner than 50:1

Trying to build an analogy using these two is not a good idea because they
do not relate to each other. Try using pipes. Same pressure in big pipe
versus small pipe ... fluid will flow faster in small pipe. Smaller number
+ faster flow like the gearing.

My mistake, I used "richer" to describe that there is more oil in a 25:1
gas/oil mixture than in 50:1. This condition may not be richer, and I used
the wrong word. In any event, the analogy is flawed when used to correlate
gear ratios.

When you say "higher" what do you mean?
(It sounds like your saying "higher ratio")

This is the whole point of my argument... 3.73:1 is a lower "ratio" than
4.56:1 (ask your math teacher).

The OP (poor guy... all he wanted was a simple answer) asked:
"1) How difficult and expensive would it be to go to a higher ratio?
(addition to my wish list)"

And CRWLR wrote:
"First, you want a lower ratio, which is a higher numeric value."

That's where I disagreed...
The OP is correct in wanting a "higher" ring/pinion gear ratio which
produces a more power to turn bigger tires, what we call a lower gear.

We all agree that 4.56:1 is a lower "gear" than 3.73:1

> Fuel/oil Ratio 25:1 is leaner than 50:1

Agreed

Man we live in an interesting world. Yes, I meant flashlight but
unfortunately it has been raining for the past 24 hours and I don't have a
covered garage. I'll just have to wait.
