Poor Fuel Mileage on 4.3 V6 with Quadrajet 17056250
tayto:
try adjusting the secondary throttle plates and/or checking to make sure the shaft isn't bent. make sure to grind the ends of the screws off so they don't snap off
Kenth:
The throttle blades are bevelled so they wont stick.
I have seen "frankencarbs" with blades installed upside down sticking.

Hmmm ok, well unfortunately I took it apart before I read this I so I guess I can't tell if that was the problem.
I am, however, unfortunate enough to have had the baseplate taken apart before (god knows why, they didn't even install bushings) and one of the screwholes is no longer a 3-48 sized hole. The threads are completely gone. Is it ok to resize it for a 4-40? Otherwise I'm kinda stuck.
Cliff Ruggles:
Go to 6-32 threads. I supply 6-32 screws with the bushing install kits for that reason. You'll also have to open up the holes in the throttle plates slightly for the larger diameter screws......
don3194:
Oh ok, I didn't know you supplied a larger size. I guess I feel better having even larger screws that 4-40 anyways.
