check the timing,also middle head gaskets blew out of those on a regular basis
is that the midnight special,with the gold trim ?mine was awesome ,back in the day…..
It sounds like the timing is off.Another thing to check is the idle circuit in the carbs.If it sat awhile they could be gummed up with varnish not letting the engine idle.It wouldn’t want to start like that either.I don’t know how you cleaned the carbs but spraying gumout in the throats won’t fix a clogged idle passage in a carb.They need to be taken apart for that.
