Are you talking the big heim at the bottom of the shaft ?
I’ll usually set it about a 1/2” out and then adjust it once the driver is in the kart to straighten out the steering wheel to their body placement in the seat, if that makes any sense to you.
For example on our Phenoms which are setup for syrup racing, the heim usually ends up being an inch or more out as everything is more to the left.
The dirt karts are closer to 1/2-5/8” out.
