Rudeboy and Gary

I'm using OS F cause I use also in all my big 2 cycles (Mokis)with success.
In the Webra I'm running 5-7% nitro fuel, 19% oil (50% castor 50% syntetic). I usually prepare homebrewer fuel 80/20 and mix with Wildcat 4 cycles (15%N-18% sint. oil). In the Mokis use only homebrewer.
Any other suggestion in glow plug?
