One prob is that the Q Jet carb is old and needs rebuilt but then again there are millions of hoses and some aren't even hooked up and I can't find where they even go. I looked for places where hoses can go into and nothing to be found. I am going to keep up with this thread and see what you come up with because I have kind of the same problems.
make shure your choke is working properly. I'v heard of numerouse accounts of 80's 305's hard starting due to malfunctioning chokes on the carbs( which is the first thing I would suspect on a hard starting carb'd engine anyway )., clean the choke and grease up the butterfly with some white spray grease, so it will unstick if it is stuck
