Unfortunately I don't know my exact rpms because my tachs aren't working right now. I may just take a handheld phototach with me the next time I run them. As for the placarded temps, those numbers are right out of the installation and operation manual.
The OVC carb is not anything new and was standard on later KFM 107Es and the 30HP 107 Maxi engines. According to Don Black, the owner of KFM, it was developed/tooled from another Delloroto carb specifically for the company and the KFM. The only adjustment on the whole thing is an idle speed screw so it's simplicity is nice, but finding parts for them can be hard. Here you can see one on a 107 Maxi.
