I have a customer with a Kohler CV730-0006 engine that has an accelerator pump version carburetor. According to PSW (Kohler Plus) it has a 24 853 90-S but the repair kit listed is for a non-accelerator pump version. I tried looking the carburetor online and it shows the accelerator pump version.
Note: The carburetor is not at hand so I can't personally look it over for identifying marks. I did see one Kohler engine earlier this year with a Walbro that an accelerator pump but don't know if it is the same carburetor.
