fitted a 1200 head to my 1400 block
1300 inlet manifold
ported / modded to fit a weber downdraft

found a few setup instructions for the idle jet which i have now setup fairly well i think, idles sweet and progression is good into the primary stage. this seems smooth with good power.

the second stage on the carb when opened up gives a fair kick to the car but by backing off the throttle slightly the car picks up even better...
so is this running lean or rick at WOT ?? i cant seem to work it out

does anyone know how to select the jets ?? cant seem to find much info, most jetting atricles seem to be for dcoes etc although this is similar in theory i suppose.

any ideas / links /help please
