Don't really see the relevance of stating that for the same price of a service you can buy a new electric mower. If an electric mower will do the job you want this petrol self-propelled mower to do, then why don't you go down that route? You certainly won't buy a new self-propelled mountfield SP470 for the same price of a service.
If it is fitted with a Briggs and Stratton engine then engine idle speed is adjusted via the metal tang that governs the tension on the govenor spring.
If it's the Chinese Mountfield engine then forget it.
Not sure what "clutch" has to do with it
