It doesn't always come to a strong consisten idle. I set the idle stop as recommended, and I just tune the low end needle to try to get a consistent idle. When I have the lsn where I want it, the engine revs fluctuate.

Initially, I thought it was slightly starved for fuel, but when I richen the lsn, the truck has much less snap out of the corners.

The top end is good, and the temps are around 225-245.
