^^ Looks like there was something foreign in there to do that

Ive got 10 litres on my .21 tuned and i cannot get it up to temp, after a 20 min final on a fast track, its hardly breaking 50C. Im running a 12% oil mix #6 plugs, maybe i have to drop the oil content a little? Ive got the thing absolutely screaming, not loading up and reading the plug and the amount of oil residue on the pipe side of the car its still very rich And every now and again (usually after "Release the cars" ) it will flame at idle, was thinking just bump up the idle but 90% of the time it will idle all day after a warm up Its got me paranoid now
