Firstly - thanks everyone for the replies, legends.
- Thanks Nath - I wasn't mowing with it so there was no sudden stop...so why would the key shear I'm thinking? I just took the carb and petrol tank off. Cleaned out the carb (boiled in white vinegar actually).
- You said worth checking valve clearance, points and condenser - any advice on what I'm looking for here?
- Thanks for the parts number for the key
- Thanks Gadge. I'm assuming the starter clutch is that hunk of metal thing sitting above the flywheel. Yeah..was wondering how to get that off. Are you saying that if I use a punch in the spot you suggested I can give it a jolt and then it should unscrew?
- Not sure if relevant but the shaft that sits above the clutch (if that's what it is) clicks when turned in the opposite direction to that which spins the blade.
- From what I gather the flywheel should be able to be gently pried/tapped off using light hammer and screwdrivers?
- Sorry for the newbie questions guys. Just getting into mowers and loving it but got a lot to learn obviously.
