Hi

Run the engine for a tank of feul to get everything hot. refuel the tanks and do a high speed pass come back in and check the lsn by listening to the idle if it idles high and then drops you have a rich botoom end and should lean the LSN by 1 hour turning it in (Clockwise).

Do another full speed pass bring the car in and listen to the idle again you will notice that it still high idles but not for a long. Keep doing Full speed passes and continue to lean the LSN until the idle stays high.

now with the engine still running turn the idle screw to the left (Counter Clockwise) you will notice the idle speed drops. Set it so the idle is nice and smooth and sounds constant the clutch should not be engaging.

once you have done this the LSN and idle is tuned and you dont need to touch them.

last of all check the HSN and tune accordingly beause your rich bottom end could be hiding a lean top end

Hope that helps

Ben
