as it turns out I am going to look at a mower over the wkend its a colt 5 complete and running ,sounds like a good buy ,this way i'll have one for spares and a runner ,and keep trying to find another engine for my mower ,got thr rear axle off but the hubs (inner half)won't budge ,and as for the old engine well might have to see if any other carby combo will fit ,same with air filter assy, just another option.
