redmosquito1 2 #1 Posted April 18, 2014 Looking for some info on the governor setup for the kohler throttle on a 416-8 tractor. Recently inherited this tractor and the governor is erratic at best. It doesn't want to rev the engine up when load is placed onto it. When it was my Dads it ran awesome, he passed and it was used sparingly by my mom, sister and brother and one day it just wouldn't rev to match the load. Well after some fiddling it would rev sometimes but not always and my mom parked it in favor of a push mower that she liked using better anyways. She moved to a condo and I got the 416-8. Well now that the weather is turning nicer I want to rectify this issue as it will be replacing my 70's c100 to do my mowing. My guess is somewhere either a bearing or bushing has failed or the cables and springs are not connected correctly. I can manually operate the governor and it works ok but when left to the throttle/choke cables it will act randomly to compensate for the load on the engine. I can't seem to find a picture of the connections so does anyone with a 416-8 kohler have a picture or can you take a picture? and has anyone experienced something similar? Thanks Share this post Link to post Share on other sites
slammer302 2,154 #2 Posted April 18, 2014 There is a metal tab on the inside the motor that's connected to the governor shaft the tab maybe broke off or the governor gear could be worn out Share this post Link to post Share on other sites
slammer302 2,154 #3 Posted April 18, 2014 Either way the motor will have to be completely torn down if its one of these problems Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,440 #4 Posted April 18, 2014 A throttle cable that slips in it's mount will cause that problem or the throttle control won't stay where you put gives the same results. A governor tries to slow the engine down and the faster the engine runs the more pressure it creates to do it. The throttle cable is connected to a spring that is linked to the governor arm and that is what increases the rpm. The balance between these two forces is the rpm you end up with. Make sure the throttle outer casing is secure at the engine end. It can slip forward in the clamp under pressure created by the governor and spring and this limits the amount of engine speed you can get. Garry Share this post Link to post Share on other sites
can whlvr 991 #5 Posted April 18, 2014 I would download the engine manual available here,it explains how to set up the governor Share this post Link to post Share on other sites
redmosquito1 2 #6 Posted April 19, 2014 It took me a minute to figure out how to download the manuals again, but I'll be doing that in a few thanks for the idea. It may be that the throttle cable is slipping, last spring I had to put a new choke cable on due to it seizing over the winter, perhaps I left a bolt loose on accident. I'll read the manual and verify it's correct. Share this post Link to post Share on other sites
