Hey guys, the motor in my 69 c10 which I don't think is original but still a 350 has a hard time with timing. If I advance or retard it still doesn't run worth a crap. I have 3 carburetors I've tried to make sure it ain't that, so I pulled the plugs and turned the crank back and forth. If I start at 6degrees btdc it turns to 4degrees atdc. Seems like a lot of slack to me, what do you think, new timing chain or is this good
