[Mgs] [SPAM] RE: setting jets in su's

[Paul Hunt]

If you already knew about the two turns down from the bridge you don't need
the dial caliper.  That needs you to remove the piston cover, remove the
spring, remove the piston and keep them and the screws safe from loss or
damage.  You then have to poke your dial caliper down the jet tube but keep it
clean and free from damage.  Then replace everything in its original
orientation, without damaging the needle.  If you do both carbs at the same
time it is essential you don't get the components mixed up.  Or you can lift
the piston slightly and turn the adjuster.  Your choice.  The whole point of
the 'two turns' thing is that it puts the jets in a position that will allow
the engine to start and run without all the fiddling about with a dial
caliper.  Two turns puts it a known distance down, same as the dial caliper
but without the fuss.

  I knew that about starting level with the bridge and screwing down two
turns.

  But, of course, that didn't answer the question of using a dial caliper.
