Recommended Carburetor Settings (Starting Point)
Notes:
(1) When adjusting the linkage make sure the throttle shutter (butterfly) fully
closes. Also, do not set the shutter adjusting screw to idle the engine as this
will cause it to run rich when decelerating or on warm up/parade laps and
make proper LS adjustments difficult. Start the engine about 1 minute before
going onto the track and gently “crack” the throttle to keep the engine running.
(2) Adjust throttle linkage so it stops at the pedal, not the carburetor throttle
shaft
