Engine Talk - Kohler 16 HP in my Snapper 1600
Posted August 23, 2010 - 09:10 PM
1. At high rev's I hear the odd miss in the engine. It is very light and is kind of random. Maybe every second or two I hear it. What could that be?
2. My engine cuts out every once and while. Usually happens after 30-45 minutes of mowing. It doesn't always happen either. It seems to start up after letting it sit for a while. I feel that it is due to overheating but don't know how to tell if it is running too hot? Any sure signs?
My guess is that it is running lean and I know that it could cause overheating. But how do I know if it is running lean? Does running lean explain both problems above? I also suspect timing but have no idea how to check that.

New plug 2 months ago - check
New filter and clean out lines 2 months ago - check
Did the best job to adjust carb I can - check
I did notice that the grass builds up quite a bit on the air intake screen. I have only had this tractor for a couple of months now and this took me by surprise! Is this common in other tractor since I have never had this kind of problem before. I was even more surprised when the operator manual suggest checking it before every use! Wow, it is a bit of a pain to clean....
I adjust the point gap from about 0.015" to the recommended 0.020" - don't know how much of a difference that will make.
Also, the new plug I put in is a H10C Champion plug whereas the engine manual calls out RH10 Campion. Would this be a cause for concern?
Starts and runs good, maybe even smoother. Will know when I get it out for the next grass cut.
