My friend just bought a '75 CJ5 with the 304 and we towed it to my house today and started tuning it up. I noticed that there wasn't a vacuum line connected to the distributor. The distributor has a nipple where a vacuum line would go. Is there supost to be a vacuum line there? If so, where does it go (manifold vacuum or ported carbuator vacuum)? We are having a hard time getting the thing to run without backfiring. I put a known good carb on since the old one looked like it's been "modified" For what it's worth, the 304 has an Edelborck intake and had the stock 4 barrel carb. I put my holly on to see if we could just get it to run w/o backfiring but no luck. I think it is something w/ the distributor. It idles OK but backfires under load (mostly through the carb).
Thanks in advance!
