This is almost funny. I just this afternoon did a search here for 129 wiring diagram and came up with and printed last post before it bacame last post. I'm playing with a 128 that strayed into my possession in a package deal and decided today to see if it would start. I've stripped it down to pretty much frame and engine. To make a long story short, unless the solenoid is grounded it just don't work! I knew that, just had to be reminded, I guess. A weak spark, an overflowing carb, and the old beast started. Can nothing short of a rod coming out through the block kill these old Kohlers??? While I'm here, I might's well mention that I have both Hank's and Kenneth's books and feel they're a must for the enthusiast. The internet is great, but a book can be forever.
