There are varying recommendations on suitable distributors for our Type IV engines with carburetors. Some advocate use of the 009 centrifugal advance only units. There are well written recommendations from "Bubblehead" and from "air-cooled.net", both advocating/explaining why SVDA (single vacuum, dual advance distributor, -- has centrifugal and vacuum advance operating independently) are the correct type as they provide some advance at lower rpm's that eliminate hesitation from idle, and give better mpg.
Some manufacturers no longer make these SVDA distributors, but fortunately others make them, including Petronix model D186504. What does the "brain trust" say? |

The PerTronix is a clone of the Bosch 034. I couldn't find the total advance for either. The 009 is known for its flat spot. A good SVDA dizzy will eliminate that as long as you run a vacuum line. Apparently the 034 has the same mechanical advance as the 009. If the Pertronix has 30 degrees of advance like the 050 it may be a good option.
