I've searched and read several threads here of similar issue as mine, and it sounds like my problem might be an ignition coil. I have a Simplicity Legacy mower with a Kohler 25. I was mowing on a slope when it started running very weak. I looked at the fuel gauge, and though I had about 1/2 tank, the slope was to the right, so the gauge was on E. I figured the fuel pickup was not getting ample fuel supply.
So I disengaged the mower, and eased it onto level ground, and worked the choke a little, which had no effect on it. Made it back to the garage, barely. I cleaned off the foam pre-screen, checked the plugs, checked the harness connector on the right side, all looked ok.
I narrowed it down to running on one cylinder, as I could pull the right spark plug wire off, and it had no effect. When I pulled the left, it would stop running. I swapped plugs to make sure it wasnt a bad plug, but the problem did not follow the sparkplug.
I connected an old Sears timing strobe light to each plug wire as it was running, and both sides made the timing light come on the same brightness.
I dont think it is fuel related. I filled up the tank, and ran it (on one cyl) for a few moments, no change. If the carb had clogged passages, choking it would have a more positive effect on how it runs, and both cylinders would be running, even somewhat intermittently. Now, only the left cyl is running.
Suggestions?
