I noticed that the HD-1D carburetor body for my 1970 CH isn't machined to accept the economizer check ball and welch plug. I also have an HD-2D that does have this check ball. Given that the HD-1D and HD-2D were both used in 1970 (Sportster and 74, respectively) I'm curious to know why the Sportster version doesn't have one. Please see the attached photos. Any insight?

Quicker revving Sportsters need a bigger dump on acceleration than stock Shovels...? -
I really don't know - I thought that was what the accelerator pump was for....??Originally posted by duffeycycles View PostBill Pedalino
