Correct spark plug is 14mm x 3/8" reach - Champion J-8 or Autolite A7.  ....If burning some oil, a slightly hotter plug can be used such as Champion J-11 or Autolite A9.

Bruce, I was under the impression that the K series used either a J19LM for long height or a CJ8 for low clearance?

NGK are the opposite....colder the plug higher the number....the hotter the plug, the lower the number.  Wish things were more standardized.

That could be.  I think every small engine could use a J8C.  A CJ8 is still just a short J8C, so if Kohler is saying J19LM or a CJ8, the J8C would probably work just fine.  I know I have used J8C across the board on most old engines. 

 

Just now looked up the number, K161 uses 41 132 06 which has become a J19LM.  I think that is nearly identical to a J8C in terms of heat and so forth, so we are probably both right.

Just for clarification:  Champion J-8 was the long plug with 13/16" hex, while CJ-8 was the shorter version with a 3/4" hex, but otherwise the same as the J-8. 

 

The J19LM was a "universal" plug for small engines, but they had a higher failure rate (cheaper quality?)  when we were selling them, so we stopped handling them.

 

A J-8J plug was the same as the J-8, except the ground electrode did not extend all the way across the center electrode.  ....These plugs were recommended for 2-cycle engines, as they were less prone to fouling.   .....The CJ-8J was a shorter version of the same plug, but with a smaller hex.

 

 I am not familiar with the J8C designation.  ...Perhaps it is just a newer numbering system for the J-8 ????

Bruce, thanks for the info.  I had heard that a lot of the older shops were not fond of the more modern plugs in use for old engines. 

 

J8 did become a J8C.
