Solid core spark plug wires with electronic Ignition.

Ok, I know an old tractor it is best to use Solid core spark plug wires. And I know not to use solid core wires in a modern vehicle. But a few tractors I have converted to electronic ignition, and the catalogs say not to use solid core with electronic ignition. I have always assumed that they just meant on a modern car/truck. Is this right or does a tractor with electronic ignition need different plug wires.

Thanks.

Doug, fer sure GO WITH THE VENDORS RECOMMENDATIONS Ive read some literature to the effect they like a lil compensation ballast (or a lil inductance from those spiral core wires) in the plug wires when they run those high energy high voltage coils with electronic switches.

NOTE these high energy ignition systems are a somewhat different animal then when we wanted wire core wires versus any carbon core suppressor wires in the old limited energy mag ignitions cuz there we didnt wanna waste any precious energy at all in the form of heat loss in resistive plug wires..

Do what Pertronix or whomever recommends NOT what we may think on here

I agree with Ol'John T.
The manufacture will be concerned either about impulse noise on radios.Or an ignition path which is a short circuit without significant impedance to limit peak current.
It's safe to run solid wires from the dist to plugs but use a spiral wound/inductive wire between the coil and the dist.
In any case you are running a low rpm, low compression two cylinder. It's not a supercharged nitro burning 9000rpm V8 top fuel dragster.
 
John you hit the nail on the head again. Spiral wound magnetic suppression is the ticket. Almost zero resistance, no radio noise and no burnt out module. JimN
