Rick,

It's not hard to do.
Start with the low needle( it's the one closest to the engine on the carb)
Turn it in 1/8 at a time and see what that does to your transition from idle.
On mine when it's cold it doesn't take throtle and feels very lean.
When it warms up after a minute or so it takes throttle with no hesitation.
Leaner than that and it won't start, richer than that and it will have rough transition after
long periods or idling.

You set the high needle for max rpms and then back it out a little.

It might be a good idea to have someone more experienced help you out while you
are doing this for the first time. All you need is patience, a flat screwdriver, and a tach.

Take care,

Stratos.-
