Hi
I have my H30 running but when I idle the engine down so the centrifugal clutch disengages the drive to cutter drum, the motor stops. Basically it want idle. I have dismantled the carbie several times checking for crud. Played with the idle screws, no help. The plug appears to be running rich! Has anyone got any advice? The engine oil was very dark so I have replaced it with some diesel engine oil so as to flush out any sludge they may have built up over the years. I figured diesel oil would be good for this as it has a lot of detergents in it! Any advice welcomed.
