G'day list

Thanks to all who responded to my inquiry about this. On Monday we had the 
car on a dyno and gas analyser, and within minutes we'd found the problem to 
be overly weak carb needles. Although the ones it the HS6s were OA6s, the 
rich needle for the 100M, the mixture was leaning out excessively after 
about 1/4 throttle. We tried some richer needles that were to hand (RH) 
which improved matters somewhat, but  they weren't rich enough so we 
consulted the SU charts and now have some 55s on order. More on this when 
we've tried them. The cam it appears isn't anything out of the ordinary so 
we'll set the clearances back to standard.
