[Healeys] Fuel pumps

[Bob Spidell]

Interesting. In all my readings about the mysteries of the SU fuel pump, that is the first I've seen of that/those methods of adjusting the diaphragm ('stretching' it); all others use the 'push the diaphragm until the mousetrap doesn't throwover, then back off 4-6 turns' method. This method may be superior in that, possibly, every diaphragm may be have a little different 'stretchability.' 

Maybe this is Kees' closely guarded secret method?

There’s been a lot of talk re SU pumps recently and some of it was related specifically to the issue of the points’ “throw-over”. I sent out a blizzard of bumf on the subject, none of it acknowledged so apparently wrong, but I can’t help adding to it with the attached pages...purely because I rather like the rather Heath Robinson approach with the use of matchsticks(!) and also the apparent confidence that one can adequately cover so many topics so briefly.
