Put my chevelle back together after I thought I had a timing issue, new balancer, timing chain, distributor, plugs and wires. I could never get it to idle right, it always wanted to die out, played with the timing and I could get it to idle fine just really hard starts.. So after replacing everything and putting it back together it fired right up, idled and sounded great! Starter went out on me and after replacing it it went back to doing the same stuff.. It starts right up now and takes it's gas but if I just let it idle it wants to die out then backfires through the carb..
