I have found that tweaking the 'back end' settings of the Spica system might help in one area, but generally don't help overall. And in time, it tends to make things worse.
The Spica system has a setting procedure that starts with the base settings and builds on them. If the base settings are not right, the settings later in the loop tend to get worse and worse. I'd recommend going through the entire procedure. The whole thing takes maybe an hour, and you'll have the pump running as well as it can. bs Sent from my iPad 3 On Mar 29, 2012, at 10:59 PM, Jason Glover <[email protected]> wrote: > Hello all, > > I recently swapped the SPICA pump in my '76 Spider for a used unit from APE. > Previous pump had a stuck rack.
