Errrrrrr...... no.....!

You are making a classis error of thinking that the steering wheel 'sets' the steering. It doesn't! Because...... it's NOT the steering wheel position that makes the kart go straight, it's the toe-in/out angles of the front wheels and the Caster angle. As a crude way of looking at it, if you release your grip on the steering, the Caster angle will force the kart to drive straight forward. The angles on the two front wheel will have set themselves to be roughly IDENTICAL: both toed-in or out identically. It doesn't matter if the steering wheel is bolted on upside down, it's the WHEELS that control what's 'straight'!

The thing to remember is that, whatever the lengths of the track rods or the angle of the steering wheel or column. (so long as those are 'reasonable') the kart will STILL track-straight if you let go of the wheel. That's because the rear axle is 'locked' and forces the rear wheels to 'go straight'. They control the direction of the kart and the front wheels will 'work out' their own angle which will be equally toed-in/out on each wheel..... regardless of the steering wheel angle

Strictly, the drop link (the bar that hangs down from the bottom of your steering column and joins to the track rods) should as close to 'vertical' as you can get when setting the tracking. If not, the action of the steering at full-lock (look up 'Ackerman angle) will be biased one way of the other.

The angle presented by the rear wheel to the front wheels is dependent on the kart and axle being straight, not the angle of the steering wheel.

So, set the steering drop link pretty roughly vertical..... and set the toe-in/out. The rest will sort itself out....

Finally, for any other techies: yes I KNOW that I am just generalising and there are circumstances where the advice is wrong but those are pretty damned rare and there is not room to go into the minutiae of these rare exceptions .
