OK. Used it to mow my lawn front and back today. No petrol dripping any more. That's good. Will only start from cold with the choke butterfly valve fully closed. Won't open on it's own. Have to open it myself by that black tab I pointed to in the picture.
I can live with that but would like what I presume to be an automatic choke system, to work as it should.
Now another problem is over revving. The lowest I can get it to do before cutting out, sounds like the highest revs it should be. When I move the throttle forward it sounds like the sky is the limit if I push further.
I would like to be able to operate it at lower revs as it is too loud and unnecessarily fast.
I presume there is a problem with the governor or there is an air leak. It could be linked to the choke function as well. There is a hose that leads from the rear of the carburettor to the crankcase and this was missing when I found the mower, so I cut a piece of garden hose to fit in it's place. This could be the problem if it isn't sealing enough on either end. It seemed to go on fairly tight but might need to fit on more tightly.
