Carburettor Sizing

Carburettor Sizing

To all: I have a guy here who has several buckets of Jag Carbs for sale.
The HD6
and HD8 are 1 3/4" and 2" respectively. Where, exactly, is this measurement
taken from? He isn't sure if he has any HD8's but I'd like to find out.
I'll let the list know whats there. - Aloha, Rob XK-140 FHC

Well, lets see if I can make this clear. The numeral stands for how many
1/8s of an inch over 1" is the diameter of the throat of the carb body. IE:
HD6= 6/8 of an inch over 1 inch or 13/4"; HD8= 8/8  over 1 " or 2"

H1=  1 + 1/8
H2=  1 + 2/8  = 1 1/4
H3=  1 + 3/8
H4=  1 + 4/8 = 1 1/2
H6=  1 + 6/8 = 1 3/4
H8=  1 + 8/8 = 2
Hope that this helps. - Ron Duncan, 670425
