Bill, do you know the series of the carbs? I have seen the 327C on the 070 and it has a 5/8" venturi and the 090`s had 244A and 324A which have 13/16" venturi in them. I guess that what you have seen then means that the 070 and 090 shared all the carbs between them. Also read somewhere that the 090 used the 331A at some time in their production run, may have been in one of my Tillotson carb Master manuals so I would have to do some reading to check that out.
