Thanks Bud. Maybe they are alternates. I'm gonna give TRF a call tomorrow
and see what they have to say. Fortunately, I don't have to make emissions;
I'm just trying to get it set up right. My carbs are actually for a 1973 and
have tubes for the vents to the float bowl to accomodate anti-run on. I have
this disabled and don't think it's a problem.
Now, do you have the restrictors or the adaptors on the carbs? Would you
mind getting an approximate size of the orifice in them to confirm the
measurement Sam made? Just the closest size drill that will fit is good
enough. If I can't get the right part, I'll make it.
