Ok then,
Yet another update..
I managed to actually rev the engine to a proper 10.000rpm
as the old bag who lives right above my underground garage
has buggered off on holiday.
The valves do both open to HI at that rpm, only thing now is
to try and work out why the valve pulleys don't move towards HI
at 2000 rpm, like they used to.
Anymore ideas Andy?
Cheers.
