Not sure what is best for 16% yet as i have not experimented with it.what plug did u use for your 16%.
i swear by O'Donnell fuel if u can get your hands on it. just last week some dude came to my track with a ten year old fresh 25% bottle and we tried it on the hyper engine and a rb matrix . it still is fresh ... well maybe the nitro content has lowered but the lubricant is still working wonders lol.
In our "Pullstart" class, we go by max 16% Nitro; I think to be consistant with Aussie rules. I don't know if I can get O'Donnell here in Australia but using a local brand 'Hot Stuff' and their recently changed formula. Its working well and has about 12% lube. The plug I used for combo was OS #8 @ 16% and running perfect. As long as the fuel comes in a plastic bottle with good seal you are o.k.. Engine temp??? as tuned for performance and ensured that body opening max size to our regs; front 50% window opening.
Who knows possibly 240 degrees F on 22 degree celcius day.
Anyone else with engine advice? Has anyone grooved head button, that sort of thing? Chasing mods for more bottom end punch.
