If you adjust your kd so it's at max when the carb is at max and it requires "fiddling", then you have the wrong arm on the trans. Any other way is wrong information that will cause damage to the trans. We don't "fiddle".. And that just so happens to be one of my favorite jokes. This thread is chock full of bad info by the original poster plus a few others. But it's the internet so some people love to suck it right up. I'll do my best to continue to call out all the mistakes but it's cutting into my rebuild time.
