sweet mate.
now when you run your model, warm the engine up, then starting with the high speed needle, turn it 8th clockwise, this will make your mixture more lean. therefor increasing performance, should notice better top speed too.
keep turning 8th turn clockwise and thrash it to test. keep doing it until you turn it that last 8th turn and the performance is not increased. then at that point, turn it back 8th turn, its tuned.
should be a nice line of blue smoke upon acceleration, if there is hardly any then its too lean, needs to be ritchened up, if there is loads and loads of smoke, its still too rich, lean it out.
and with the low speed needle, run the engine, warm it up, thrash it for a few secs to clear out excess fuel in the carb, bring your car to a standstill and squeeze the fuel line, it should run for around 2 - 3 seconds, slightly speed up in revs then die, thats when its fully tuned.
if it runs for more than 2 - 3 seconds then its too rich, lean it out a little, again with 8th turns.
if it just dies quickly when squeezing the line, no speed up in revs, just a straight die, its too lean, ritchen it up slightly
tuning can be quite tricky, different fuels can help.
i never run model technics, worst fuel around, i like optfifuel
remember, when tuning 8th turn clockwise leans it out and 8th turn anti-clockwise, ritchens it back up again.
good luck
