If it has spark and still won't fire on starting fluid sprayed in the carb this is your best bet. If you don't figure it out send me a message or something and I'll come over and give her a look. I'm getting familiar with Kohlers finally, just rebuilt my kt19 for the 919 I restored and it's kinda rubbing off on me but I still like my Briggs :D Anyways first thing I would try is new spark plug even though it looks like good spark I'd still try that because it's easiest. Second thing is deffinitely check, clean and adjust the points. I've had one that showed spark but wouldn't run until I got the points adjusted right. -Fred

What brand spark plugs are you using? I find Champion plugs tend to give out quickly. Had much better luck with Autolite plugs. Champion plugs won't last very long in my old antique farm tractors I collect. I use either the Autolite or AC Delco and get much better results.

Better then 75% of no starting can be attributed to a faulty spark plug regardless of brand. It is an electrical item that can fail at a snap of a finger. That being said, try and collect an exchange unit for the new one that failed, ugh!!!!8C

well pulled it apart and everything looked good the key not sheared as a matter of fact it still looks new but I have to ask when should the points open is it when the S mark is showing on the line and how far open or the T and how far should it be open also could reuse the head gasket or should I get a new one it only has 10 hrs on it

well I took the motor out ripped it down and nothing put it back together put back in tractor hooked it up hit the starter and it fire up only thing I changed was I did a static timing and haven't touched it since will run it tomorrow and see what happens now that I think about it all my problems started after I used a timing light to set the timing after a static time was done does that make sence because thats all I got

Hi, I wouldn't worry about the .020 gap. If the timing is right this is what you want. It the camshaft is worn and you adjust the point to .020 you will change it out of time. Timing is everything, point gap is only relative. Al Eden

Put the throttle at idle and try to start it. I have had several Kohler engines that would only start at idle when hot. If you opened the throttle any at all they would not start.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
