Where to bend Choke and Throttle rods

[Scott H in Wheaton]

I just a new set of choke and throttle rods and they are straight as an arrow. My old ones were mostly just curved but look like they have been bent, unbent, and rebent several times over the years.

Are there measurements about where to place the bends or do I just do some mock-up and hope I get it nice looking the first time?
