Youre saying add 15% gasoline to FAI fuel? Does the power compare to nitro fuel and how about the idle?

Could you give me some info as to why a soft mounted engine will trash the bearings quicker?  I've been running Hyde type A mounts without a nose ring on my DZ's for a couple of years now.  All of my engines have been back to YS and all have had the bearings changed, some twice. I didn't know that they were bad, thought maybe they changed them just because they were in there.  Did notice that the old ones they returned were always rusty.
