Greetings group,
Something new has started in my engine and I'm not sure what else to do. When I hit the gas hard, the valves are rattling. At first, I knew it was timing, as we discussed here a few weeks ago and when I backed the timing off to where it should be, 7 btdc almost 30 full advanced,
009 diz, everything was just fine. Bought a tank full of cheap gas (I know...stupid) and it started again, not as bad but bad enough to notice. After about 150 miles I decided it was bad gas so I filled up again with the good stuff. Got better but still very noticable. I filled it up again after another 100 miles or so and it's the same.I adjusted the valves and put in new plugs and points this weekend. I've really only driven it to the store and back since because of all the rain this week but it's still rattling away.
Any suggestions?
