I have a new carb purchased on Amazon for my Deere L110 with a Kohler Command 17.5.
The new one looks all correct, but something bugs me. The choke plate is wide open as expected with some tension to keep it that way. (This is without the carb connected to any linkages.) But! The choke actuator arm (with the little torsion spring around it) only moves about 35 degrees of arc until it stops with the choke plate only about 35 or 40% closed! And the choke plate has 3 largish relief holes in it. It appears to me that when the linkage moves the choke plate to a hard stop it is caused by the choke plate hitting inside the Venturi bore. With the holes in the choke plate and the choke only closing to a 40% closed angle it does not look like fully choked will restrict airflow more than about 25%.
Is this normal? I figure you can tell I don’t do this for a living!
