Thans so much for the tip. This morning, I took took off the CB again, and I actually adjusted the screws to 0.75 turns in, and I actually like the feel of the launch. It is rather high for loose dirt, but for grass, the tires actually grip really well. I feel like it is about a 7000 RPM launch, maybe 7500 launch. If I get tired of the rooster tails when launching it from dead stop on loose dirt, I will back out to 0.50 turns in like your setting.
Here is one of the shoes of the teflon set
BTW, this is the set that I bought, PN 18620/2
