Turned the idle **** up till it was reving high when running let off the throttle and it cut out. Tried to start and it would not fire up till I pushed the throttle in a bit. Then reved high as expected turned it down same thing. I think it is the sensors not sure how to check though. I'll recheck the cable slack. Right not its about 5mm of free play at the throttle, see if I can get more out of it.
