ok o I'm having some running issues and i posted this in the chat thread but i wanted to post it in here to get a few ideas. It started this a few months ago, i cranked it up and it was misfiring. i made it about 30yards down my driveway and it died. changed the cap, rotor and ignition module and it still wouldn't start, but if i advanced the timing it would run. so I changed the distributor cause it was knocking when I was adjusting the timing. So new distributor set it at 0° timing and it idles great but if you give it throttle it'll pop back thru the intake and it will not restart if you kill it. if I set it 18° advanced it runs good and I can rev it and it sounds great but when you put it under a load it detonates and looses power. And it won't go over 40mph. it has a new distributer and new spark plugs. So what I'm thinking is maybe slightly low fuel pressure causing it to run bad, but idk. so I'm going today and getting a new fuel filter & plug wires. Then if that doesn't do it my next move is to check the fuel pressure. any suggestions?
