Self inflicted Kohler M16 Problem

[snowhound 106]

I wanted to check the valve settings on my Kohler M16 and was good about taking notes and photos as I disassembled it until I got to the reed valve I didn't take note of how the plate that holds the reed valve in was mounted. Does the high spot in the middle go against the reed valve or should the high spot be to the outside away from the reed valve?

Ed, after you get the valves adjusted, be careful when snugging down the valve cover. If the "M" engines are like the "K" engines, you can warp the valve cover real easily. Then it will leak oil forever, or until you replace it with another cover (like I did).

Thanks for the replies, I did take a look at the PDF at the Kohler site but the photo quality was poor so I really couldn't tell which way the part goes on. I guess I will have to try it the way that seems to be the most logical and hope for the best.

Ed,

The guy who rebuilt my K241 a few years ago reassembled the breather in "the way that seemed to be the most logical" to him at the time, and got it absolutely WRONG.

Just a friendly suggestion -- do yourself a favor, and get it right the first time so you don't have to pull it back apart and do it again too soon.

I would try to find a parts manual for the Magnum on the Kohler site, or look at the parts diagrams on some of the online parts supplier web sites. Or try a search on "crankcase breather" on RedSquare. Or wait for somebody who has a photo or diagram handy for exactly that model.

I'll post a link in a few minutes to a thread I started a while ago on my own breather assembly, maybe the set up is close enough for you to make an educated guess at how yours is supposed to go back together.

Later...

EDIT:

Here's the thread I was thinking about, there's a nice diagram in the second post, maybe yours is similar:

Thanks Ed

I went to Parts Tree and found a diagram, have it back together but still having what seems to be a compression release issue.

I did see a recent post about checking the voltage draw of the starter I'll give that a try.

Yep, thats the thing i screw up the most when reassembling engines is the breather, I printed the page out of the service manual about a year ago and hung it above my work bench along with specs, makes the whole process alot easier.

[snowhound 106]

I also printed the diagram for the breather so I don't make the same mistake twice, I checked the voltage draw and it is fine so it looks like I need to go back in, I did find a thread about small balls of plastic in the valve area and some very small ones getting into the compression release keeping it from operating correctly. I did find some plastic when I check the valves so I guess my next step will be to look much closer at the compression release.

Again thanks for all the replies

Make sure the oil sensor has not come apart and disintegrated. Just helped a friend rebuild his and found that the sensor float and totally disintegrated and pieces were all over in the engine. There were alot of them jammed up around the ACR and the springs. This was on a Mag 16.

At this point I feel that is the problem, I did find some plastic when I checked the valves.
