Subject: SU carb needle markings.
i have 2 SU carb needles marked eother "RG" or "BG" wich are very "trick"
i'm suspicious that if they are not a competition needle from BMC that they
might be from robert (bob) griffith of BHP development. does anyone
still posess the needle charts i remember seeing somewhere in the shady past
of rather long ago to possibly verify this?
considering a richer running bugeye....
