If you grab both sides of the damper you can usually turn the damper side to side & fell when it picks up the extra load of the can etc to see if the timing chain is OK

Had a similar prob once, the intake was loose, sucking air.
Sniper, 493/383, Firmfeel, RMS Streetlynx, Speedhut. Dana, 4 gear.

First thing I do when I tune an engine is check intake & carb bolts

Carb bolts tightened when I changed to the new carb. Tightened in the proper criss-cross pattern as directed. As for the intake, I've checked the bolts and they all seem tight. Going to check for leaks there next.

I recall in previous posts that you were struggling with holding an idle at all. Now the ignition and carb have been changed out to no avail. It sounds to me like the timing was out of whack from the start. Charging a carb and swapping ignition parts really won't change any of that. I agree it's time to get to basics. Find TDC and if you have the ability set #1 up 10 degrees advanced. Then see if it will fire and warm up. After that get timing set then tune.

I'm in Libertyville area and am happy to help if this is not familiar for you. Timing has such a huge affect on these beasts!

Thanks for the advice. I've done all the checks for vacuum leaks so timing is next. I'm glad I changed the carb because the old one was pretty worn out. A Holley tech told me the numbers on the date code show either 1981 or 1991. I'm guessing '81.
