If you have spark and fuel, I would think it would at least run, even if poorly. However, I did see a post a while back where the throttle position sensor was the culprit. Maybe someone else can chime in with something more helpful.

thanks maxpower, Ill check that out, I think the fault lies in too much fuel, after 5 turns the piston has a pool of fuel on it!!!! will recheck all again !!thanks

How strong was your spark ? If you have a weak spark and wet plugs. It won't fire.

You didn't fill that thing up with Diesel did you ?
