Fix'em all 49 #1 Posted July 14, 2018 Can anyone help please. I have got my recently purchased K181 engine running but I think the carb needs the mixture screws setting. There are 2 mixture screws that I believe are low & high idle & an idle speed screw. I am not sure which of the idle screws is which (one on top & one at a 45 degree angle on the side).
