The belt finally went on my Flymo. In this video I will show how to replace it for under £5 and some of the problems you may encounter doing it yourself.
Good tutorial. Very real life situation. I had 4 rusted screws. Used the Dremel to cut slots in 2 of them, drilled another out with HSS bit, but couldn't touch the forward most screw. It is possible to slip the belt on with the last screw still attached. I tried a screw extractor set, but it wouldn't touch the steel screws. Refitted the motor with a set of brand new screws in case I need to fit a new belt down the line. Pig of a job either way.
