Hello Bill, I don't think I have the original carburetor it is a H 30/3 Pict Solex and the distributor is a 009 (no vacuum advance). Did the car originally come with a vacuum advance distributor?
I placed the inline fuel filter above the drivers side rear axle. I have been changing it every other 3000 mile oil change.
