My Kyosho DRT was running and starting ok until a while back. The only way to get it to start now is to blow down exhaust pressure tube to put lots of fuel in the carb. The engine then races at full speed and can only be slowed by covering air inlet with a finger. My needle settings are all as per manual which worked fine in the past. I've dismantled and cleaned the carb but its still the same. The engine seems to be leaking fuel from somewhere, though I'm not sure wether its near the exhaust manifold or somewhere. It may be coming out of the crankcase at the clutch end. I'm going to take engine from the car , give a a good clean and see if I can find something obvious. The other day I had the car running ok , accelerating ok and top speed ok with plenty of smoke but the idle speed was way to high and erratic. what should I be looking for ??? Should I try harder to set the idle speed and the low speed mixture ?
thanks
