110cc Single Tao Motor with 3 speed trans. What axle-sprocket tooth count should I run?

Two Questions:
1) Is the right angle turn in the bung important? Or can I just flow the fuel straight down?
2) How did you find the bearings for so cheap? I'm looking at replacing one of mine (it stuck, but works with heat and WD-40) but cheapest I could find was this: SKF - 1-3/16" ID x 2.4409" OD, 3,380 Lb Dynamic Capacity, Insert Bearing Insert Bearing | MSC Industrial Supply Co. (mscdirect.com)

I found this for $15, is it a good deal?

It is if you have a 1-3/16" diameter axle.

I do. It's weird.

The right turn fitting was what I had on hand.
I get my bearings from carquest. Just looked up the size in the book.
