Make sure the one you get has an internal resistor.

Never saw one with a resistor attached to it but that doesn't mean they don't exist. I just get one with the internal resistor. You have everything you need and it looks neater.

I would guess that what you heard in your coil was the oil sloshing around.
Most of them are oil filled. and they have an air bubble in them to allow the oil to expand when it gets hot.
I would recomend that you switch to an epoxy filled coil because of the vibaration of the single cylinder engine.
Epoxy filled internal resistor coils are not easy to find localy. I bought an external resitor Borg-Warner and I don't know what it really fits.
This older guy stood back and watched a greenie bring out about 5 coils and I would shake everyone and hear the oil slosh. He finialy got off his stool and walked back to the shelf and brought me what I wanted.
I installed a Ford ignition restor between the key run terminal on the key switch and the coil then I ran a wire from the starter side of the switch straight to the coil + to help with the voltage drop while cranking. I don't think that is really necessary down here on the Gulf Coast. Up north when PK's are used to fight that white stuff it should help getting them cranked.
Kirk engines sells a Bosh internal resistor epoxy filled coil.
A good friend of mine said he read it was not good to mount an oil filled coil horizontialy because with the air bubble at the top some of the windings are not covered by the oil and the oil also cools the windings. Is that true? I don't know. I do know factory coils mounted horizointialy on Kohler engines don't last very long.

If you have an amp gage on the tractor, that could be your problem. I just went through that myself.

If the coil says (12v stamped on it) it has the internal resistor already. Here is wiring diagram.
