Hi all. New to forums, but I've been lurking for a couple of years. I love this site. My question is this: new 350 long block, new carb and coil, new plugs and wires. I get run on unless I turn it off in gear. I've tried everything. So I took it to a mechanic, and he fixed it. After 2 days, it starts again. He fixes it again (says he's just adjusting timing). After a couple of days, it starts again. So, I figure timing chain is faulty. I change it, time it, and TA DA! No change. Still get run on! Before I give up and just buy a whole new engine, is there something I'm missing here? I've checked all the vacuum stuff, checked the carb, etc... Any other suggestions? Oh yeah, it's on a '76 with all stock componants under the hood.
