Idle problem
dlphil10:
The screw I believe you are talking about is fully seated (the small screw behind the tube)

I apologize for all of the additional posts...
I just test drove the car and the carb seems to be fair. The only big issue is a bog upon part throttle. It doesn't have as much power as I believe it should have either. Could this be due to the lean jet/rod combo?
dlphil10:
I found two quadrajets in my dads stash that are in need of rebuilding. One is a 67 and the other is a 69 or 70. Both are chevy quadrajets he has acquired. One pair of rods are stamped 44B, and the others are stamped 42B. The rods stamped 42B are stamped in the middle of the rods while the rods stamped 44B are stamped towards the tips of the rods.
Would these rods be suitable candidates for my build?
Cliff Ruggles:
I don't like using used jets and metering rods for custom tuning. Very few used jets will pass a pin gauge test, they are almost always "egg" shaped and worn some. Same with used metering rods.
I would call the shop when you get time and get new jets and metering rods for it and PP spring for what you are doing. Since you already have good rebuild parts in it should be good to go and nothing else needed to get it dialed in....Cliff
dlphil10:
Primary rods, jets, and secondary rods are ordered. In the mean time, do you think its an issue that the screw (Idle air bleed screw im assuming) is fully seated?
