RE: [alfa] Alfa Mechanic in Northern Utah or Sourthern Idaho
Jeffery - Another question?? Ok, here goes . . . .
Good accel, but cutting out under partial throttle could be a broken
compensator link retaining spring. To check it, remove the SPICA air cleaner
box. Then, on top of the injection pump, you'll see a triangular plate with
a short stud and nut sticking out. That is the barometric compensator (BC)
bellows assembly. Remove the three countersunk machine screws and carefully
withdrawl the BC. It's not attached to anything inside the pump. Be careful
with the BC. It's somewhat fragile, so you don't want to drop it. Put it in
a small box on top of a rag or something and protect it from inadvertant
damage. Next take a flash light and look inside the cavity that the BC is
in. You'll see a spring about an inch long. It should be attached to the
compensator link arm at the bottom and the machine screw that goes through
the FI pump body at top. It's ok to press on it slightly to make sure it's
attached both top and bottom. A broken spring will be pretty obvious. If
it's broken, often times it breaks near the top and you can remove the small
broken piece and reattach the good part to the top screw. If this is indeed
the case, it's easily done yourself. When AlfaBB comes back up, theres a
thread with pictures on how to do it.
