Kohler M160s

Recommended Posts


You are showing a 9 digit serial number?? In 1985 Kohler went from an 8 digit s/n to a 10 digit s/n.

Assuming that this is a Magnum engine (which I believe started about 1985) it should have a 10 digit s/n. If the first 2 digits are correct (20) your engine is a 1990.

15=1985, 16=1986...20=1990...25=1995.

Can't wait to fire it tomorrow as it looks in great shape with a lot of compression .

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
