Hi,
It would help to know your engine number to determine what year that is. Often older cars have newer engines in them.
If you have the original engine...
It should be between # 921 247 - 945 526,
If so the following information should apply to it.
You should have a Solex 28 PCI
If you disassemble the unit, make sure you put the venturi in properly. the narrow waist should be at the top, it is easy to reverse and it will fit, just won't operate properly.
Also take caution with the float lever, oben must be up.
You should have the nylon float instead of the brass one.
Your Venturi should be 21.5 mm dia.
Main Jet 122.5
Pilot Jet 50
pilot jet air bleed 0.8 mm dia.
air correction jet 200
pump jet 50
pump air correction jet 50
Emulsion tube 29
needle valve 1.5
float weight 12.5 g
pump feed .40 -.55 c.c. per stroke
You should have the clamp on oil bath air cleaner
Good luck
Dave
