I have a Walker 26EFI MT mower. I have small oil leak that the best i can tell is coming from somewhere around the top and leaks first in the area where the throttle cable attaches to the throttle. Is there a sensor that might leak or is it a gasket?

How can anyone tell you without...
1)crystal ball
2) pictures
3)make and model of engine

Kohler Pro 26EFI.

It could be the oil pressure switch. It is in that area and they are prone to leaking.

There is also a breather plate in that area. The gasket could be bad. You need to clean the area and determine exactly where the leak is coming from

Here is a link to the service manual for your engine

Thanks

be sure the o-ring hasn't fallen out of the dipstick tube cap

Omahatiger did you get your oil leak fixed. I lean towards ericg about an oil sensor up top or breather plate. I ran a 26 on my mt for years before doing away with it and putting in a 20 horse. I replaced the breather plate gasket it leaked oil and made a mess like your picture was showing. Only oil leaks I have dealt with are a couple side pans or crank seals on both sides or the breather plate on top. That is the way my 26 looked with oil mess when that breather plate gasket went bad.
