hello all

im very new into rc cars and i have a nitro GV BV-1 it has a force .12 motor on it, when i start the thing it starts with out to much hassle but as soon as i remove the glo starter it dies, i have tried replacing the plug, changing the mixture 1/4 turn at a time, i left it on for a while warmed it up then held it reved it a couple time thinking that maybe there was a build up or something, i have cleaned the tank brought new fuel, clean out the lines? what next? also there seems to be only 1 adjustment screw on the carbi, do all carbi screws work the same? as in clockwise leaner anti clockwise richer? and where is the idle screw on these carbi's do you think that could be to low so doesn't have enough go to keep kicking over??
