I saw a few posts (and I thought actually Elvis, from the above post, mentioned this in more than one post that I can't seem to find anymore) that said the "EGR port" is the ported vacuum line that should be used, and that the adv ported vac. On the Weber, the EGR port is capped from the factory. I figured I would post on here to first make sure my vacuum lines are at least hooked up correctly, and then go from there. I talked to a buddy recently and he suggested maybe the HEI wasn't installed correctly and that's why TDC doesn't seem to be working like it probably should be (as he says backfiring from the carb is always because of poor timing). I redid TDC a few times and it still does the same thing. That's when I tried finding TDC, in which I now have backfiring from the carb. I had it running a bit rough without most of the emission lines hooked up, but once I got everything plugged in (as shown in the attached diagram) it seemed to only run for a few seconds before dying. I ended up seeing quite a few posts that suggested upgrading to the Weber 32/36, so after cleaning up the BBD and failing emissions I decided to just grab the Weber. The previous owner had done an HEI upgrade and I believe a nutter bypass, but it was idling very rough with the Carter BBD. I was hoping someone would be able to recognize and point out the errors of my ways.Īs some background, it is an 86 CJ7 that I bought a few months ago as a project jeep to work on with my 13 yr old son (something we can both learn and then he can take it over at 16). I have tried following the below post (along with a few other similar ones), as well as the below diagram links, but I can't figure out a few lines (particularly the ones in green on the attached diagram). As a resident of CA, I really need these vacuum lines working properly for my registration. I have found so much great info on this site, but one common thread is how quick everyone seems to be to dump their emission vacuum lines. First time post and first time Jeep owner.
