Is there any difference in valve spring length on the Mark 2 compared to Mark 1.
The new springs measure ,Outer 44.5 x 29 mm , inner 39 x 19 mm, that I have brought.
The old springs measure on average ,Outer 40.4 x 28.7 inner 36.7 x 19.7.
The easiest way to clean the rocker spindles was explained by a member using a strand of brake cable , thank you.
When blowing out spindles there were small bubbles coming out of the alloy plug at end of spindles , I think they may be pressed in , not game to drill them out.
