Cid Vance 1 #1 Posted September 3, 2020 Am in the process or rebuilding the Kohler K-161T on my WH 704. The spec shows a bore of 2-15/16". My engine measures 2-7/8". I have a Kohler K-160 that bore measures 2-7/8". Seems as if Kohler made a running change on the K-161 to increase bore size. Also the 2-7/8" bore K-160 list horsepower at 6.6. My K-161 also has a fuel pump which I believe go be diaphragm operated as the is no pump lever. Are these pumps still available? Thanks...Cid, Mass I'll llon, Ohio Share this post Link to post Share on other sites
ebinmaine 72,671 #2 Posted September 3, 2020 Just in case I haven't already said so somewhere else, welcome to Redsquare!! I can't answer your questions about the piston size but I do know those diaphragms for those vacuum type pumps are available from one of our members. @buckrancher Brian. Him and his wife switch between two houses during the summer so be patient with getting a response from him. Share this post Link to post Share on other sites
