mc1960 43 #1 Posted July 25, 2018 What is the maximum RPM you run on Kohler engines? I think the book says 3600 but that sounds to high, 2000 sounds pretty fast to me. Thanks, Mark Share this post Link to post Share on other sites
Racinbob 10,256 #2 Posted July 25, 2018 3600 is correct. They will run all day at that. Besides, you need the rpm for most pto run attachments. 1 Share this post Link to post Share on other sites
WHX?? 46,678 #3 Posted July 25, 2018 I bought one of those cheapy RPM meters off fleabay for setting RPM's but I think I got what I paid for! Kinda like some of my employees.... it kinda works when it wants too. While we are on the subject anybody know off the top what minimum idle RPM should be. Heard you run them too slow might not get adequate lubrication? 1 Share this post Link to post Share on other sites
oldredrider 2,547 #4 Posted July 25, 2018 Minimum RPM for non pressurized oil systems...1200 RPM. 1 1 Share this post Link to post Share on other sites

But the reason I repeat it is to bring to your attention it isn't only for lubrication reasons but for airflow and cooling reasons. 1 1 Share this post Link to post Share on other sites

tunahead72 2,332 #7 Posted July 27, 2018 (edited) Just to clarify... Are you actually measuring your engine's RPM with a tachometer, reading 2000, and thinking it's running too fast (in which case maybe the tach is faulty, or not hooked up properly, or something)? Or just thinking that 2000 RPM "sounds" too fast for a small engine to run? Edited July 27, 2018 by tunahead72 Share this post Link to post Share on other sites
tunahead72 2,332 #9 Posted July 27, 2018 In that case, I would be cautious. Your engine may actually be running at 4000 rpm, which would sound (and be) too fast. I'm no engine expert, but there is something about the way Kohler engines fire and how some tachs pick up and display those signals. Can somebody else chime in here and clarify how tachs work with Kohlers? And @mc1960, can you give us some details on your tach and how it's connected?
