Mountfield Hp470 And Rover Raider 375 Petrol Lawnmowers

The Mountfield HP470 starts but will stop going after 10 minutes use, I have no idea why but maybe an easy fix. The rover will not start at all and I have broke the pull cable, both were working just 6 months ago and someone with the knowledge will probally get them going in no time. The Mountfield seems to have hade some DIY on it on the wheels such as screws to fix the height. Any questions feel free to ask. Offers welcome. Happy bidding. Collection from Stembridge near Martock
