Help with a Q jet

<< < (2/3) > >>

raguza123:
I can get it to high idle around 1500rpm's but when I bring it down to a normal idle 750rpm's it will stall unless I close the choke plate a little.

I found this morning that when I did the throttle bushings, I never lubed them in any form, I was reading about how the pump spring should close the primaries, well mine wouldn't close at all, I lubed them with WD and it closes now on the pump spring and my secondarie's were hanging a little , now they close.
Are the secondaries out of adjustment? and they could be the issue?

raguza123:
I cleaned the shafts out with carb cleaner and put some drops of oil and worked it in.
I got her to start and run at high idle and then kicked it down and she stayed running.
started with the idle mixtures at 5 full turns out, drove them in all the way and backed them out to 4 turns out
it didn't affect the idle or try and stall, and at 4 turns it smells rich and burns my eyes.
APT screw is at 3 turns up, but she's idling, I am getting a slight pop out of the exhaust, means my mixtures screws are set wrong?

raguza123:
I been told I should have gone with a earlier Q jet, because this one is emissions calibrated and is lean because it's an EGR carb.

 The later carbs are better in general. If you're looking to keep it stock, then an eariler carb with Cliff's kit/parts might be best. :D
