Listers :
Having just collected this info for a friend, I thought I'd share it
with the list :
location Whitworth wrench Nearest SAE (inch) equivalent
throttle coupling clamp 1/16W 1/4
fast idle cam bolt 1/8W 11/32 (ignition wrench set)
float bowl mount bolt 1/4W 17/32 (if you can find one <g>)
float bowl cap nut 1/4W 17/32
FB mount stud/nut 5/16W 19/32 (got mine at Sears)
mixture nut 5/16W 19/32 (also in SU tool kit)
Damper cap 7/16W 13/16
Note : I am not sure when the changeover from the stud/nut float bowl
mounting to the bolt mounting occurred. I believe the stud/nut was used
on AUC 768, and the bolt was used on AUC 878.
If 13/16" is too snug on your damper cap, try 21mm. That's the only one
where a metric size was close.
