[TR] Carb O-ring Question????

[Harrymague at aol.com]

Started preping my car for the Dayton BCD and the rear carb has  always 
lost the damper oil.  So I took it apart.  This is not the  first time I have 
taken this carb apart to get to that little O-ring.  Well  going thru my 
parts, I couldn't find a replacement for it.  So I went to  the several spare 
carbs I have, open one of them up to look at the O-ring.   What I found 
surprised me.  The O-rings in the old carbs were square, but  the replacement in 
the carb on my car was round (the profile of the  o-ring).  All the companies 
list this o-ring, but I am curious as the  proper application.  The orginal 
part number is listed as:   RTC165.  Any bodies toughts would be helpful.
