I dont remember ever making D-81 decals, but I will be searching my old drives tomorrow. I've had a lot of custom requests over the past 19 years, so it is possible.
After looking at acto picture and reading this reply of yours, that makes sense.. someone once sent me the Kohler 181 digital manual so i can properly set the governor timing .. I need to find that link again so i don’t blow up the engine with too much rpm
