Hi to all who have assisted so far.
The state of play now is that I have received the new clutch parts and painted them up. I have removed the engine and decided to buy a new Honda. I thought the engine shaft look damaged as it had a big gouge out of the side where the cotter pin must have slipped on it at some stage. I wasn't overly happy with the way the engine was performing anyway so decided to bite the bullet. I am in the process of backlapping the reel whilst I have the engine off. I have gained some practice on this on several old handmowers this week and very impressed with the results from what is a simple procedure.
Any tips on reassembling the clutch? I have gone with a grub screw version rather than a cotter pin version. I have a new bearing to install in it and I assume this just taps in with some encouragement?
regards Tim
