Spark problem?
 

I picked up this 123, it would run but only with throttle in certain positions. Had a rear axle shaft leak, and when brake pushed down, the hydro is just barley
engaged. Fixed oil seal, took carb off, cleaned and kit. Adjusted brake and hydro. Now I have no spark. Have power to positive side of coil but nothing after, spark plug will not spark, nor points. I wired safety wires together, still nothing? Has to b a bad wire is all I can figure. I have changed plugs, wires, coils, condenser, points, nothing. I'm sure it's minor, just driving me nuts!

Here is a simplified Kohler Ignition Circuit Diagram..... Ignition Circuit

Do you have a good ground connection...??

Everything checks out good, but no spark. Pulled everything of of a running 123, it will not spark on this 1, put parts back on the other, it runs !!!! Starting to get annoying! Been messing with it off n on for about 3 weeks now, has to be a wire, is all I can figure

OR a bad ground....

Had a similar problem and found out it was the point wire was touching the cover on the inside. Just a thought.:bigthink:

try a new coil and condencer. i did that on my 124 and it ran like no tomrrow.
