Hard to start after a few days of non use

My 1983 CJ7 takes a lot of cranking time to start after a few days of sitting idle. If I start it at least once every 5 days or so no problem. Battery is new, and assume starter is fine since problem only occurs after a week or so of non-use. I'm perplexed! Any thoughts? Thank you

How do you finally get it to start? Do you have to prime the carb with some gas or just keep cranking it until it starts?
Could be a fuel pump or a fuel return line causing it. I had both with my 1978 CJ7 over the years.

Jeep hard to start

I just keep cranking and finally it catches. If it is fuel pump, or fuel return line, would it manifest itself like this, just a problem in starting? Cause after it starts everything seems to work fine. Thanks for your thoughts!

Just went through this with my 1981. If it sat for more than a week it would take multiple times to start. Put a device up by carb that prevents fuel from going backwards as I thought fuel was draining out. Replaced fuel pump, all of this over several years. If it sat for awhile it would take it forever to get primed to start. Just yesterday I replaced tank and fuel lines. Pretty sure it was fuel line corrosion causing fuel lines to have less flow. If I put a gas can on ground and took fuel line leading to fuel pump, it would start right up. Not sure I needed to replace fuel tank but at 38 years old, it probably didn't hurt. Fuel lines is my bet.
