The plug doesn't change anything. I've done it for years, decades. You can ignore all the marketing hype of what they print on the jug. Isn't that amazing? Decades ago, there wasn't a designation anyway. It's all marketing and your engine will be fine, especially a .45 size.

I ran 15% nitro 2 cycle fuel in my Saito 50. Low nitro could be a problem because your engine could run hot, especially if you push it hard.

I've never over heated a 4 stroke engine because of fuel selection but I haven't tried FAI. That's a mixture / tuning problem. Simply richen it up. Lots of bench testing on this.
