K161 Stop Pin

[bsb369]

I'm working on my K161 in my 1961 original and no matter what I did I couldn't get the governor to set properly. I started looking at the engine for possible causes and noticed that the PO had apparently stuck a bolt in the block where the stop pin goes. My question is can I install the proper stop pin in without tearing the engine down and could this be the cause of my engine wanting to run wide open? As always thanks for any help.

on a 161 the stop is behind the governor arm, you loosen the brass nut and rotate the stop to adjust the speed. check the manual if you're not sure. you can down load it at kohler engine site

ok well there is a threaded hole near the cross shaft that has pin type phillips head screw in it. What is the purpose of this screw?

that keeps the governor gear from falling off of the pin inside the engine.

oh ok....well that doesn't sound good....can I install it without tearing the engine apart? That would probably explain why the governor isn't working?

if the governor fell of the pin inside you will have to at least take the pan off, I've changed them on 10 and 12 hp Kohlers with the engine assembled and its time consuming but never tried on the smaller ones.

I found a picture online of the screw I'm talking about. Its the long screw about the brass nut in the picture

yep, that's the one that holds the governor from falling off of the pin that it rides on

I was afraid that was what you were going to say lol. Thank you for your help I really appreciate it

if the governor assembly did fall off it possibly did other damage. it drives off of the cam.
