No, that doesn't make any sense at all. Higher resistance = less current draw by those components. Take the plug wire off (infinite resistance) and it will still crank exactly the same as if the plug wire were connected. The condition of the ignition circuit has
nothing to do with the cranking system. If the plug and/or wire were bad, the tractor wouldn't run.

For instance, if wires were cut and spliced, then soldered without being wrapped, then some of that electrical current is lost as it is passed down the line to make it's connection. Here's an analogy, it's like you are going to your local cub dealer to buy some hy-tran to help improve the performance of your cub, but you decide to stop at McD's and service your Big Mac attack. Then you head back out to the dealer and there's a very nice looking babe having car trouble along the side of the road, so you stop to help her out. Afterwards, you head back out to the cub dealer and see a Super GT along the side of the road and you stop to ask, "How much?". Then you head back out to get the hy-tran......and an hour later you get to the dealer and find it's too late and they are closed! That's like the electrical current on it's mission to starting your cub......only a little embellished with my stupid story. The insulation makes sure that it focuses on its mission of getting there as efficiently as possible, without any distractions.

Nonsense. The insulation is there so the wires don't short out against each other, the tractor's frame, etc. Current is not 'lost as it is passed down the line' with or without insulation. The current in a circuit for a given voltage depends on the resistance of the circuit, which is not affected by the insulation on the wiring.
