Thanks Bruce,
Have just taken off the cowling only to find someone has had a cold chisel to the nut not much left of nut ,is the nut part of the starter cup? its a 160 with a green body the only reason i may have to get it off is that it caught fire the other day i had just primed it and pulled the pull starter only to get a spark jump down to the body where a lot of dust had garthed and was a bit oily so when i primed it the excees of primer petrol went on dust etc and caught fire,so i may need to replace spark lead from inside under flywheel unless i mght have to replace the whole assembly,graham
