Fuel for this .29: Back in 1950, can I assume that there was no nitro in the mix? If so,would it have been a straight 75-25 methanol to castor ratio? I can't seem to get it started on the 15% nitro blend I have on hand. Lots of odd popping sounds, and in one case, the prop nut blew off in an apparently backwards firing.

Any suggestions from the good and kind minds here?

I always made my own fuel. 70% alcohol, 25%castor oil, 5% nitro methane swinging a 9/8 wood prop. I have run Torps for over 47 years. The prop and % of castor oil won't make sense to anybody under the age of 60 or so.
