Kohler Twin Question

[SS MAYFLOAT]

Trying to figure out how the coil pack on the Kohler twins work. It has one set of points that feeds one coil that has two plug wires.<br /><br /> Tried a regular coil with two plug wires in it, but it of course pops through the carb. Trying to figure out how it switches the spark from wire to the other.<br /><br />New coil cost around 100 bucks and hate to put that much into this mower since it only cost me 200 to begin with. Old coil is dead shorted.<br /><br />Any ideas?

It fires both plugs at a time, one cylinder on exhaust stroke one cylinder on compression stroke.

Clanton is right. The same way a big v twin HD fires. Both at once.

Re: Kohler Twin Question

So, a regular coil should work? Huh?<br /><br />Tried it earlier, but it started popping through the carb. I'll check the compression to make sure the intake valve is seating. But it was running/starting great before the coil shorted out. Dang on gremlins, gettin into everything around here.

run a leak down test. a lot of those big Kohler twins had a compression release on the cam.

SS MAYFLOAT<br />regular coil won't work. The plugs are actually connected in series.
