WB-Sim 172SP not Starting

Today I ran into a different but related problem in attempting to start the WBsim C172. I'm using the Honeycomb Alpha yoke, and I've been using the magneto switch on that to start the engine. The problem now is that in the WBsim C172, when I turn the switch to Start, in the sim it keeps flicking between Start and Both, over and over repeatedly. As a result, most times the starter isn't on long enough between flicks to get the engine turning up to enough speed to get it to start. Even if I have the Battery Off, i.e. it isn't cranking the engine; the same flicking misbehavior is happening in the magneto switch in the sim.

Yet when I load in the Asobo Classic C172, the magneto switch behaves as it should i.e. if I keep the physical switch on the controller to Start, in the sim it stays at Start. I checked for any other controller programmed for MAGNETOS START function and there is no conflict. And I'm using exactly the same controllers setup for the Asobo Classic C172 in which the flicking issue doesn't show up.

This might have been occurring occasionally before on the WBsim and I had put it down to a weak battery or some such issue, but now that I have looked closer at it I have spotted this flicking switch in the sim display that has gotten so bad today that the engine will not start. And it happens even after I have connected the battery cart and let the battery voltage come up to 27.4 V or higher.

 

I went on the WB Sim #support Discord channel and posted the problem. The developer quickly pointed me to a fix that needed just one parameter change from 0.1 to 3. I used Notepad to do the edit, but I've now downloaded the free utility Notepad++ that someone recommended to me on the WB Sim Discord, which actually would have made that editing much easier! BTW, it's essential to follow every detail in the solution which is at the following web address: https://discord.com/channels/955520899094818886/955524866407297075/1256132000775929946

After I made that edit to that line of code in the XML file, the starter switch works fine and the engine now starts reliably.
