I'm having a horrible time getting the correct timing/fuel mixture for my 76 Sb 350. I have an RV cam, Quadrajet w/750 CFM and low rise intake. It seems no matter where I set my timing the engine/exhaust smells like fuel. There is no leak in the carb though, so I know it's burning way to rich.
I have the idle adjustment screws set at 2.5 turns out and the engine idles at 850-900 RPMs. RIght now my plugs are pretty black and that is just from playing around trying to get the timing right, maybe one trip in the woods.
I mentioned my problem at autozone when buying my new set of plugs, and they helped me get a cooler/hotter (which ever one was what I needed) plug to try out.
I'm just frustrated with the tuning. I don't konw if 750CFM is to much combined with the low rise intake which does'nt allow for much air/fuel seperation? And from that, no matter what I do with tuning it is just going to run rich?
I tried to set the timing at 10-12 but it just (for lack of a better word) chokes...The engine sounds best at (guessing) 20 deg advanced. I'm guessing because that is obviously way off the timing bar on the HB.
Sounds like a mess, any suggestions?
