At least you have confirmed it's not mechanical or fuel related. Now to fix those electrical gremlins!
Don't you love it when you get to "practice" pulling engines and replacing starters?!
yeah. the original one had a sticky bendix, I had bought a pile of NOS, OEM Kohler stuff from a guy on CL that was ~50 miles away, guy was cool enough to ship it... lots of good stuff in that box. One thing that turns out isn't as good as I thought was a brand new starter for a KT/Magnum series engine. I had to take it apart as I remember and built 1 starter out of 2 (the original starter off this machine makes 3) I had one sitting here that was shorter in length than the brand new one. I do not remember what I needed off of that extra short one. but the brand new one had a corner cracked off of one of the magnets fastened to the inside of teh starter case, but since I took the broken corner out and still had "most of" the magnet intact I thought it would be fine. but, no.
So now I gotta yank that starter and swap the end caps and bendix off of that one with the bad magnet and swap them to the original one, which worked but seemed a little "draggy".... hopefully raiding all the good parts from that new defective one, and swapping them to the original one, will net me 1 good starter. This will be the 3rd time pulling that engine to deal with starter issues.
