Hi Grumpy - the machine is running OK & yes I will replace the governor spring to improve the max speed. See attached close up of the sprockets, the smaller ones are much sharper on the tips. I am assuming I need to replace all the sprockets & chains (have done this on motorbikes before) - so assuming it not that hard. Where do you suggest I source the parts from & what would you [Linked Image]
