Good lord my bad

The drive train on my kart would be able to handle the sand very well

Wide off road tyres and wheels size:
145/70-6 (14 tall, 5.7" wide
Heavy duty steel rims and 4 stud bolt pattern.

Those tires and rims aren't very big in the typical fun kart scheme of things. They should be fine and knobby tires are usually easier to source than slicks or ribbed. What could matter is if the tire profile at max inflation presents a square/flat profile or if it is rounded like a bicycle tire. *Rolling resistance.

If you intend to have the kart driven in deep sand, loose dirt and the like, that changes things a little, like Panchothedog said in post #18.

No the tiers are just a little bigger and have paddles. Also, I have an extra two baring in the middle with a three speed transmission that I machined

We encourage everyone here to make their own threads for their own builds/own projects. If you would do that and add photos galore, that would please a great many gearheads here who want to see what you got.

In other words, pics or it didn't happen!

Ok more pics, you can see the laser line is horizontal with the front bottom timber and now got to do the back so everything sits level i.e, axle wheels, subframe and ground.

TIMBER!

Right. Add that sketch and the way you intend it to look and the forum can provide some parts sources. What kind of landscape do you intend for the kart? Pavement/sidewalk roads, grass, dirt, rough stuff?

You’re in good hands with Functional Artist though.

The build thread for my Torsk kart is "packed" with info
...& that may help with your build
