I have and old cub 147 hydrostatic tractor with a 14 HP Kohler engine which I rebuilt many years ago with no operation problems. The problem I am having is that lately when starting the engine it tends to kick back. This started about a year ago and was not as prevalent during the warmer weather since it would start. I live in New York state and I have noticed in the late fall this problem started to rear its head. I tried checking the points thinking they gap may have opened slightly however the gap was set at .020 as is required. My next thought was maybe it is the fuel since summer and winter gas has a different formulation. Today March 23 the temp was up near 40 and I tried starting the engine but it would only kick back and not start. When I noticed list last fall I thought about the ignition process. If your points open to early the spark is present way before top dead center of the piston travel and that could cause kick back. I experimented by closing the pints slightly and this seemed to help but not enough to warrant leaving them slightly closed, thus I changed back to the factory required .020 gap. My question is has anyone experienced this problem and if so does anyone have any explanation as to what might be the problem and what steps should I take to correct this problem The engine has been fine for the last 8 years since the last overhaul.
