Several questions glow plugs?
It seems that all of my OS Engines run the best with an OS Number 6 Hot Glow Plug. Before I switched to the number 6 hot plug, I was running the fox long plug with idle bar. I don't know why I could run my OS .40 ABC Max for years with the fox long plug with idle bar, and now I've had the best luck with the number 6 short plug without idle bar on my .61s FX, and the .46 AX. I think I want to retry the fox long plug with idle bar in these engines. Is it safe to put a long plug in these engines?
I'm not complaining, but I don't understand why OS charges so much money for their glow plugs. And I don't understand how come fox doesn't make a hot, medium, and cold plug? Are there any other manufactures that make glow plugs?
