S Timing Mark
 

Thanks DX3! I'm going to the shop today, so I'll check it out and post reply later, maybe with some pics!

S Timing Mark
 

Timing Marks found!!!! Thanks to all who posted!
Pics show T and S marks. Highlighted marks with paint! Hopefully, someone else can find it useful. Not sure why they would hide the sight hole behind starter/generator bracket!

My friend was able to perfectly time my 104 without using the sight hole at all. He just turned the engine over by hand and felt for it. After his work, it started right up and runs smoother than silk. Gosh I wish I had his talent to work on engines!:beerchug:

S Timing Mark
 

Still do not understand why Kohler would make the sight hole and timing marks to show on the opposite side from the points. Then on top of that, hide it behind the Starter/Generator bracket. That makes timing with a timing light an impossibility. I really like Kohler for a well built engine but what were they thinking.
Anyone shed some light on this.
:bigthink:

This is from Brian Millers web site
"On Kohler flywheels, there should be a T and an S stamped into the edge of the flywheel. Place a bright colored paint mark on the S mark [punched line] on the flywheel. The S mark is located exactly 20° BTDC (above) the T mark. S stands for Spark Advance, which is where the timing is set if the engine is equipped with a one-piece camshaft that has a compression release mechanism. T stands for TDC, which is where the timing sets if the engine is equipped with an older two-piece camshaft with an automatic timing advance. The flywheel may need to be cleaned to see the timing marks. If there is no visible S mark, then it's located exactly 1-5/8" (1.625") above the T mark. Steel flywheels with no timing marks must be degreed-in to create new timing marks"

One of the things I've done in the past is to use the points, as someone previously mentioned, to get the marks in the ball park of the hole. Then get yourself one of them big ol hard gritty ink erasers like you used to get in grade school. Shape the eraser down to fit it in the hole and press it in there against the flywheel and rotate the front pulley back and forth to clean the flywheel up. Take the spark plug out for easier movement. No guar-un-tees but it has worked for me Once I find it I set it right on and use a paint pen and make a mark somewhere on the front pulley and one at the same point on the block. Then if I have to look for it again I just line up those two paint marks and BINGO, there it is.
Hope this helps someone else.
