   Bill,
   A number of the old SU pumps, fitted to Jags and Morris needed the
   odd impact
   to keep them running.

   Exactly. I had to keep a large rock in my Morris Minor
   for that purpose.

No arguement Colin!
For the record my dad owned a XK-150 S Jag. Three huge 2" SU carbs
thrust into the right fender (or wing if you prefer) a horrible pain to
work on, but a cool car.
