a) Set idle gap with idle stop screw to roughly .5mm.

b) Set HS and LS to flush with the end of the housings.

c) Fire up engine and blip throttle to warm up then let come back to idle. Adjust LS needle to get smooth steady idle. Leaner = higher idle, richer = lower idle. Adjust this until you get a smooth, steady idle. Do not touch the idle stop screw only use the LS needle!

d) Toss the car on the track and adjust the HS needle to get the top end performance that you want/need.

e) Finally pull the car in and adjust the LS needle one final time (probably richen it) to bring the idle speed back down and you are done.

That's all that you should have to do and you should be done!
