[NSRCA-discussion] Activities for a Sunday ,, was Too Quiet

[Bob Richards]

I remember reading (Clarence Lee, I think) that detonation due to lower octane is not a problem in the smaller engines. Something about flame propogation...  Of course, this is the same person that said for years to use low nitro, low percentage oil in four-strokes, and also not to run them inverted. :-)  Of course, I've known people to use white gas in their ignition engines and never have a problem.
 
I've been told NOT to use 100LL fuel. Again, there are people using it seemingly without problems. 
 
I've heard so much conflicting information that I don't know what to believe. Unless I can run the engine with some on-board sensors to measure the performance, temps, etc, I think I'll stick with the manufacturer's recommendation.

Some people use it, and it smells good.  However it has an octane rating of somewhere around a 66-69.  This will almost guarantee detonation problems on a pipe.

Anyone use white gas?  And does it have the same power as regular gasoline just not all the additives?

Avgas..... Pleasant smell. A little pricy at 4.95$ per gallon. (VBG)
