Hi,
    I use a bar with a notch, hook the spring on the bar, put the notch on the frame lug and lever on. See Utube link at about 27 secs, a nice young lady will show u how...

Hi,
    The standard is 5/8", the mm dimension was rounded up. The oversize guide usually increases by +2 thou increments.

Cast iron or bronze guides in:

Cast iron cylinder head: 0.001" to 0.0015" interference fit.
Aluminium cylinder head: 0.0015" to 0.002" interference fit.

I have the guides professionally fitted, reamed after fitting and seats cut at the same time as its very unlikely the new valve guide and valve will match the existing seat line. I then lap them myself.

Best wishes...

Hi Ian,
          I cut and use 1.5mm Gore GR gasket on my A65 primary and rocker cover. Thinner for elsewhere there's nothing better....

Hi Adam,
              The best option is no doubt use a modern fuel tap, I have done so and by the posts many others have.

As Julian mentioned ethanol is a powerful solvent that, without a suitable additive, attacks many fuel system components including zinc and galvanised materials, brass, copper, aluminium, seals and hoses, cork, polyurethane and epoxy resins. In other words, almost everything used in a vehicle made more than about 20 years ago.

If you are trying to keep the original taps, replacement cork plungers. Or keep the external original taps modernising the seal material, you can have the plungers modified with a row of Viton 'O rings' in place of the cork.

Best wishes...

Hi Andy,
            I agree with Julian.

Plus you might notice a clunk sound when applying/releasing the clutch and during acceleration or deceleration.

Hi Adam,

Hi,
     Good news.

Usual issues are - When fitting the springs the spring prongs should cross over. There are 2 different return springs your year is the 68-3125, earlier models is the 68-3084 - may make a difference, as would cheap reproductions.
