moe1965 738 #1 Posted July 22, 2023 I'm working on a 8 hp Kohler and Im Wonder if this pump is missing the arm or is it a vacume type pump. It was running fine but smoking a little and I was taking off the breather to look in there and had to take off the fuel pump to do so .I just want to make sure nothing fell in my crankcase. 1 Share this post Link to post Share on other sites

WHX?? 48,815 #4 Posted July 23, 2023 (edited) Kinda odd that a 8 had them ain't it? Thought it was just 161s and below had them. 181s had the offset lever style? Someday I'll get it figured out! Edited July 23, 2023 by WHX?? 1 Share this post Link to post Share on other sites
