Just a little FYI/Note for those of you who do this swap. I saw someone else in a different forum have the same issue of car starts, but won't rev.... it could also be related to the person who isn't getting any fuel from the motor. If you look at the lower retaining plate with the 1st spring (base), you will notice 2 horizontal lines stamped on the metal. These are very important
Without any assembly on the car, ballpark idle settings on the idler on back of pump, fuel enrichment screw, and back the stub all the way back and tigten the 10mmx40mm nut to the shaft. Fire the car up, run out (or walk depending on how bad the idle is) and turn the 10mm nut with a wrench forward and backward, revving the motor. set part of the idle with the rear idler THEN the max fuel screw, rev a few times, and set the nut to where it sounds like its idling just a bit low. Turn off the motor, look into the shaft of the nut and see where the cutout is on the top of the govenor armature. make a mental note of where it is, unscrew the nut, then set the plate down with the 1st imprint lined up to the slot. (furthest back setting in relation to lowest idle). If you don't do this, like I did idiotically.... you can't rev the car, and you think that you did something wrong
- at best, you'll screw the max fueling screw wayy the hell in to compensate, but the car will still feel like a dog, and not really do what its supposed to do. And, while you do that, you'll rev the car, and have the idle studdenly climb really high, really quickly, making you crap in your pants, which is what happened to me too
Just did the govenor mod on my early aaz, and i must say- it feels a bit more powerful, but not anything insanely crazy (i've done a LOT of pump tuning that can be done externally to maximize fueling. I def. blow more smoke now, haha, and I'm ok pleased. The only reason why I did the mod is b/c my IP head seal was dumping fuel like eating a spicy burrito and having to go to the bathroom the next morning with flames shooting out of your butt. No more leaky IP = Yay. A bit more power = yay. My new hoses not getting ruined in 5k miles = Super yay. Need to hose them off to prevent any more damage.
Cheers!
