Ok, I'll try new oil seals, points and condensor.
Yes, I had the piston off, needed a clean to get the new rings onto it and into the cylinder.
How do I get at the oil seals? Obviously I need to remove the engine from the deck, and take the fan off the top. But where to from there? (Sorry, I haven't had that part of the engine apart so I've no idea how it goes together under the fan).
What sort of prices can I expect for the parts I need?
thanks for your help!
