Hi thanks grumpy,
I have cleaned out the old carb with carb cleaner. But when I have re assembled the mower still won't run. It will start on full choke but die when the throttle lever is moved towards the run setting. It will cut out even on full choke after a while.
The carb really was in bad condition with both the choke and throttle plates stuck solidly.
Would I be right in saying that as it runs to an extent on full choke then the carb is supplying to much air and not enough fuel?
I think the small jet in the centre of the carb is the problem. The larger one I can see is clear but the small was badly blocked and not even the carb cleaner seems to be solving the issue.
Is there anything else you could suggest?
