And to reduce wait times for our customers, we usually have all 4 variations of rebuilt HS6 SU throttle bodies with new throttle shafts in stock.
B18B or D? Does compression have a significant impact on needle choice?

I have all the parts for the HIF6 linkage. I actually have to find a linkage and springs to make the HS6 carbs work.
