Well its not all wrong...just not clear enough for the noobs
Also, you mentioned nothing about engine temps and the stuff you said about low speed needle is incorect. I suggest you both have a look at the Break-in Bible
and the Tunning Bible
. I don't know why the Admins have not pinned them on the Nitro On-road forum, as well as, the Off-road.
This should help you get a better understaning of not only "how to adjust", but what the different needles on the carburator do, as well.
