1863. Kohler CH18 throttle issues.
 

Hi everyone this is my first post.

I completely rebuilt and restored my '92 1863, along with a fully rebuilt kohler CH18-62509

I've got an issue however, my throttle control is funky. Holds itself at full throttle, doesnt want to idle down. New governor gear was installed internally. I'm lost now. I've tried every adjustment possible.

I will attach some pictures to maybe aid in my diagnosis.

Thank you,
Patrick

Either you hooked up the linkage incorrectly, or it is not adjusted correctly. Not a hard problem to fix. Look at the linkage, figure it out and fix it.

Hey Patrick!
Welcome to OCC
A couple pics would be good. You might just have the sensitivity set wrong. Lets see a couple pics

The governor's sensitivity adjustmentwon't keep it from idling down. The throttle set up will.

Just figured spring could be pulling all the time if it were positioned incorrectly.

If the throttle isn't set right, yes..... but the sensitivity position is irrelevant.

Did you adjust the governor to spec?

Who installed the gear?

There should be a picture here. I tried adding it as an attachment. Let's see if this works.

Yep. That's a pic of the throttle and choke linkage/mechanism.

You didn't answer the questions though: Did you properly set the governor shaft?
If not, you need to do that.
I keep my original opinion that you don't have the throttle linkage adjusted correctly.
And yes.... the governor spring is set too sensitive. While that is not the issue, it's too far back on the governor arm. Third hole from the end if memory serves, but you need to check the manual. Move it to that spot BEFORE you calibrate the linkage.... but after setting the governor shaft if you didn't do that.
