OK...all the bits have arrived, so I'll be taking the mower up to my sister's boyfriends workshop (he runs his own car mechanical business, so he has all the tools we'll need to do it) on Sunday to do it all - bore hone, new rings, full gasket kit, valve lapping and cleanup, new spark plug (the old one gave up on the weekend), oil change, adjust tappets, etc.
He said it may be worth doing the valve seals as well. Does the GX160 have valve seals? I haven't seen them on any parts lists.
Also, does anyone have the full service/workshop manual? I have downloaded what is available of this forum and from Honda and the Honda one has the tappet clearances, but not torque settings, etc.
Also, if someone wants what I have to upload to the manuals section, let me know.
Ben.
