working on a sb 350. Got the car running and running good. Put the timing light on and find out the timing is way advanced. Adjust the distributor to bring the timing to where it is supposed to be, now car wants to run like a pice of junk-- backfiring thru carb and won't idle---. Only way it runs is way advanced. Any ideas? Also while playing with the timing it backfired thru the carb real hard. graemlins/angry.gif Now sound like #2 is not firing at all. Hear a poping out exhaust. Again any ideas? :confused:

Thanks in advance for any help

Is it vac, advance dist.?Got it pluged?

oops, sorry graemlins/clonk.gif now feel like an idiot. I checked it with the vacuum hose off. Same thing? I just can't seem to get this timing thing down. :mad:

check to see if your TDC mark is correct.
