I have a Country Clipper "The Boss" 60" zero-turn riding mower. Don't have the engine specs with me right now - they're at home and I'm not - but I do know it's a Kawasaki. I was mowing the other day and I hit a small bump and the mower died. I was able to start it back up, but a bit later the same thing happened. Now it won't run at all. It will turn over when I crank it, but when I release the key back into the run position, it dies. Checked all the standard stuff but everything's fine. I did replace the ignition switch because that was one of the likely causes the dealer told me about when I called him, but that wasn't it. The way it happened - when hitting a bump that bounced me around in the seat quite a bit - makes me think it might have something to do the kill switch in the seat, but I'm sure there are other things to consider too. Any thoughts?

I have a Murray OHV-175 riding mower and it is not getting fuel from the carb bowl. I have cleaned the jets out and ran a hotwire from the battery to the afterfire silenoid (just to make sure) and also taken the silenoid completely out and plugged it. The bowl is filling quickly. It will fire if I put fuel directly in the intake. Thanks
