Morning Steve,
More stripping and checking the wee minx into the early hours!
Thought the top end rattly when purchased. After fitting new rubber band and replacing all the right hand side bits in the correct order, went for a look under the rocker cover.
Gorilla snot over everything, crushed spring beneath breather on nearside front of cover, should this stepped breather be free to slide? See little point in the spring if it isn't.
Tappets were set at 0.5mm inlet and 0.6mm exhaust! Bl**dy maracers! I know they need to be 1.0mm when adjusting the valve timing, but! PLEASE CONFIRM TAPPETS 0.1MM (0.004") FOR BOTH INLET AND EXHAUST?
Ta, Bill
