Didn't do so well today. Got a second and third place finish. The track is a clay track. Progressive pulls have created a gravely consistency to the surface. As a result, you start digging trenches early on. I am thinking about reversing my tires. Does anyone think this will help?

And pull the loose dirt to the center of tire? Bad idea.

no, you don't want to do that. you need to find a way to deal with it. try to hook it in better right away, better balance. tire psi, draw bar distance from the center of the rear axle (that's a touchy one), gearing. no matter how long you've been pulling you always get those tracks you struggle on. just have to try to make the best of it

Spinout
 

Watching other drivers, I have noticed that sometimes they spinout early in the pull. The tire I am watching almost stops but the engine is still revving. That means the tire on the other side is spinning. Short of welding the differential, is there any way to prevent this?

What axle and carrier are you running? It's easy to shim the spider gears tighter but, if you are running the stock axle and carrier I'm not sure I would waste my time doing that. Your other option is to shift your weight to the side that is spinning. Make sure your air pressure is the same on each side too. Make sure you are using a good low pressure gauge to check the pressure too.

My problem is, I have a habit of wanting to look at my tires. This shifts my weight to the tire I am watching and the other side spins. Think I'll practice not watching them or figure out how to watch them both at the same time without shifting my weight.

you don't want to watch tires. you want to sit square in the seat. if you lean back, lean straight back unless 1 tire is an issue. most people when they lean back tend to transfer weight to the arm they are holding on with.

Another thing that I believe helps it is to get all of the weight that you can inside of the frame.

inside and low to the ground

Agreed I now fill our belly boxes up first and forget about the weight in there.
