Big Ed,
I purchased a TT 91FS somewhere around 2001 and it had a twin needle carb. I don't think it was ever released with an airbleed carb. I got one of the early 54s and it did have an airbleed carb. (That one required some throttle barrel work to get it to work right.) I thought (as of a few years ago) TT started putting twin needle carbs on the 54s...? Can't quite remember. CRS disease.

Yeah, I'd like to have one of those 75s! Perfect gap filler between the 54 and the 91.
Any reviews out there yet?

Jeff
