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.
