AC Weller Engined Cars with SU Carburettors

[Robin A Woolmer]

For needle selection there is a site which compares various needles for a given jet size '  www.mintylamb.co.uk/suneedle  ' This came from an MG Octagon Car Club Site.
   Its worth a look as it graphs the various needle sizes with each other.
   If you have trouble locating the site put the address into a search engine!
