Recently since I put my heads back on to change the gasket. I timed it and advanced it to 12 degrees. So now it has a hard time starting. Basically it will start but won't stay on unless I leave my foot on the pedal to keep up the rpm steady. And 2-3 minutes later it idles fine. It idles at 750-800 should I bring it up more to 900 ? And when it's idling I also hear a ticking sound. I'm missing one bolt from the driver side of the headers. But the weird part of this all the driver side exhaust is basically smoking. White smoke. Nothing crazy but I see the white smoke. The right side exhaust is fine though. Drove it around the block and no smoke from what I see from the rear view mirror but when I put it in park in front of my house the smoke came back. Help me out Guys.
