Yes, the TSX-241-C unit was declared obsolete and all kits, TISCO anyway, are made for the TSX-33 and TSX-241-B Models now. Original Carb Float mean value setting was
shown as 9/32, +/- .016 approximately. Later M/S changed the value to 1/4 and all FORD manuals after were then listed at 1/4. The TSX-33 Model used a knurled
slotted screw Main Jet Adjustment and the Throttle Idle Speed Adjustment used a thumbscrew to adjust. These were two major changes made on the TSX-241 unit. My theory
is this method would cause many burnt hands as you had to reach in to adjust. With the new TSX-241 adjustment screw you could use a screwdriver away from your hands
and a hot engine.
