ill be a monkeys uncle , ive never seen em but they do exist , parts smart don't show em at least not that i could find , might be a kit a guy could put on if he felt the need , i wonder if they are a flat tappet (solid ) kit humm might be , have you seen them b-4 ? i thought all kohler valve in head used non adjustable , i like the first design in the pdf , the one on the top left with the rod through the rocker , seems they would stand up better , have seen them , i did pull my hair out on a kohler 20 one time the thing came in with a dropped valve , i just thought the retainer came loose (governor) set at like 4500 rpm. anyway i done a valve job slapped the motor back on started it and ran for about 2 minn , done it again . so i tore it back down everything looked ok used putty on the pistons turned it over and sure enough interference , turned out the gear on the crank had turned , it was just pressed on , did not like that design , had to change the crank to fix , looked like they would have used the woodruff style , this could be a possibility on "buzzers' " , but i guess it could be the valves . possibly wet dry should tell something shouldn't it ? ,,,,,,,,, you are right man i have seen them on command 15hp yeppers , all that carb spray must be taking its toll on me , aint nothing right on the left side of my brane and on the right there aint nothing left , thanks 30
