Default Ignition Coil in VH4D

Hello. I'm Marcin. I'm from Poland amd sorry for my English language. I Have Bobcat 720 with Wisconsin VH4D Engine and my engine have a problem with Ignition system. After a few hours of work, the coil is very hot. 3 coils have already been burned. Currently, I have a coil mounted from an old motorcycle (12v, 2 ohm from primmary) and performs well, but it is still quite hot. In my country, I have a problem with buying parts for the Wisconsin engine. Does anyone know what parameters should have a coil and what resistance?

I put a ballast resistor on mine and have not had any more problems.

The one I use is for a Dodge car circa 1970. When I get home tonight I'll look up a part number.

I thing i found problem. Somebody replace the rotor contact of distributor. This rotor in my distributor is to small and can't touch electrodes distrubotor cap. So if between rotor and distributor cap is a gap the electric current have problem with flow.
