Then tune it by ear with a cold motor while the gauge ball valve is set to read control pressure.
Put the little tool Brian gave you to raise cold start control pressure during cold starts on the WUR and disconnect the electrical plug from the WUR so it stays in cold start mode.
Start the motor and quickly turn the little allen head clockwise that draws the cold start adjustment slug in the WUR upwards to raise cold start pressure and stop when it runs smooth and isn't too rich and you can blip the throttle without it hicupping or hesitating from being too lean.
You have about 20 -30 seconds to do that after a stone cold start before the combustion chambers and pistons get hot and want a leaner mixture to run right.

Do the same thing again after it completely cools off overnight.
If you have experience you can tune CIS beautifully by ear if it isn't too far off just like a carburater.
