needle valv dimensions

[JEEPRUSTY]

my carbs have a 2.5 seat
does anyone know what the dimensions are on the bs type push in o ring valve are?

mine looks identical to others but sudco does not list it.
i have read too small an orifice leads to potential for fuel starvation and burned pistons.

i put mt cheap caliper on the o ring grrove and get an odd 7.62 mm

Float needle valve? O-ring for the inlet valve at the float? Nessism knows the demensions. See here http://www.cycleorings.com/ for the o-rings.
Needle jet?

just the float valves chef
i just need to know that the overall dimens are the same as say for an 850

the darned o rings are suspect
read a scary article on using alternate replacements with too small an orifice and therfore reduced flow.

I have valves and o-rings.
All the BS CV carbs use the same inlet valve and o-ring.

Good thing, because we don't know what bike he's talking about.
