Engine runs 1/2 to 3/4 throttle

[Randy G]

I have a JD L110 with a Kohler Command 17.5 hp engine. The mower only seems to run a little over 1/2 throttle. If I turn the throttle to slow the motor dies. I cleaned carb, blew air through lines, checked the in line filter, filled tank with gas but no change in performance. Worked fine the last time out. Any ideas?

Did you clean the idle circuit in the carb?
Model number of the engine will be helpful. should be on a shiny silver tag.

CV4918. I did not remove carb from motor but cleaned all ports and bowl during process.
