There is no absolute requirement to use Stihl fuel though they claim better results, something lots of users agree with.

I suggest you read the manual again to ensure you have exactly followed the instructions. If you did and it won't work there is cause to return it to the dealer. While an older machine often needs fiddling with a new machine should not.

One thought - if the dealer's demonstration was very short so the machine did not warm up thoroughly, it is possible that fouled the spark plug and that would serve to make restarting difficult. It would be wise to check the plug and ensure the spark is ok...

One wire is ignition module kill (primary of a magneto) and the other is ignition module frame (engine block).

The two wires run separate to the kill switch which is a momentary single pole.

make sure your air gap from the coil to the flywheel magnet is .010. if it is then take the ground wire off the coil and see if you have spark then. if you do then your ground wire is grounding out somewhere. process of elimination form the coil to the switch.

Set the gap between coil and flywheel to 0.010 inches, if possible disconnect the stop wire from coil to eliminate that part of the circuit. If spark, reconnect stop wire and check again with stop switch in the on position, should still have spark. If not there is a short in the stop circuit.

According to Stihl's engine service manuals, when the engine has no spark or a dramatic, sudden loss in power, the problem could lie in the ignition system. The ignition system ignites the fuel in the engine for proper combustion. When the spark isn't firing correctly, an influx of gas can bog the engine down or cause it to not start at all. Since you are dealing with potentially lethal high voltage, extreme caution is advised and safety gear should be worn at all times.
first Slide the rubber spark plug connector off of the spark plug. On most Stihl's this can be accessed from the top of the engine, underneath the chain brake handle. Unscrew the air filter cover and remove it, if you can't see it on top of the engine
then Insert the socket wrench onto the spark plug and remove it from the engine. Discard the old spark plug and replace it with a new, identical spark plug, which will be recommended in your operator's manual. Make sure the spark plug is gapped according to your manual's specifications or else the engine won't start.
after that Turn the ignition switch to the "On" position. Insert the spark plug into the rubber connector. Make sure the chain brake is disengaged by pulling back on the black chain brake handle, which runs atop the saw's engine.
Hold the rubber plug and spark plug, with gloved hands, about 1 to 2 centimeters from a metal point on the engine block. Wipe any flammable gas or oil from the metal spot on the engine with the rag. Tug on the starter cord and look for a blue spark across the "hex" part of the spark plug,Check to be sure the wires leading to the "On-Off" switch aren't tangled or touching a metal point on the engine if there is no spark, Replace any wires if they are damaged or corroded
