well yea ive got this cen ct4s and there many problems with it so can someone help.

problem number one is that if i start it the engine will only idle for about 30 secs but then stop unless i rev it ( is this normal), plus ive seen that the idle screw is all the way in

2. after like 5 mins of use if i keep reving it at full , the engine will cut off or if i let go of the throttle the engine will also cut off, is this due to overheating<
also i have tried to tune it but its taking ages and the engine still stalls,

other problems is that that that there is smoke coming out of the cooling head, and some fuel (from where the glow plug is,
and also if i dont use the car for like 1 week, the car doesnt move until i rev it alot and then it starts to move slowly and gains speed later.

so can anyone help please... does anyone know some default tuning seeting i can put it in
thx again
