The 3173 is listed in the Haynes ZS manual as 68/69 TR250 175CD-2SE emission 
carb. I always thought 
the F and R meant Front and Rear, but according to the manual, some TR6 carbs 
are labled R and L. 
Don't know what the 232 and 233 mean.

The manual lists the 67/68 TR250 carbs as 3150 F and R

I have a another set that say 3337R and 3337L  both have 2034 on the tag as 
well. The manual says 
they are 71/72 175CD-2SE.  The one with an R is in the front. FWIW -- maybe 
nothing.

I'll check my original TR250 carbs tomorrow.
