Checked the valve clearances all looked about mid way on the required spec so pretty good. I think the top end is pretty tidy looking allround. Only issue is while doing all this I managed to break one of the spark plug boots off the wire... it looked old and coroded inside anyway so probably due. Has anyone found a good source for ignition wires for these? Oh wait does the ignition wire just sit in the boot theres no actual hard connection so it probably fine if I just stick it back in??
