  1. By spraying out of the primary I meant when I pull the throttle. It seems plenty healthy, almost like too much. Idles just about, if not perfect. Just acceleration is the issue. As soon as I get time to work on it again I'll be checking the timing etc.
  2. I'll get into it to check the valve lash. I'm gonna pull the carb back off too and I guess clean it again. It almost looks like it may be getting too much fuel. It's spraying pretty heavy out of the primary. Pulled two plugs, they were both pretty black. And they're new plugs
  3. Well it's got plenty of fuel shooting from the primary. Think maybe too much? Air/fuel mixture maybe off?
  4. Far as I know the lines were all put back in the right place. Labeled them and replaced them one at a time. Checked the manual I have to be sure, and everything looks good. Feels as tho the timing is set fine but I don't have a timing light. Idles fine, which is why I'm leaning away from a clogged jet. Does that sound out of the question? Ha. And I'm not sure what the valve lash is.. Btw thank you much for your replies!
  5. Well it's not bogging when I go around corners, I can't even drive it ha. It's bogging when I hit the accelerator at idle. I'll give it another look after work. Any tips on cleaning the jets properly/effectively?
  6. So I picked up a 1981 Datsun 720 with a z22 engine recently. It starts and idles perfectly fine but won't accelerate without bogging out. I pulled the carb and rebuilt it with the help of a few diy's (I've never worked on a carbureted vehicle). Got it all back together and replaced all the vacuum lines. I'm still having the same issue. I'm noticing if it's idling and I pull the throttle, the secondary isn't opening. If I do it manually with a screw driver or sonething to push it open, it revs perfectly. From what I gathered by pulling this thing apart, the secondary is operated by vacuum from the secondary diaphragm. I had also pulled that apart to check for tears or leaks but it looks fine. And pushing the rod in, it pumps air out the small hole. ANY ideas on what my next step is would be very helpful and appreciated. This is fairly new to me haha
