Default hard to start?

I am wanting to sell my 85 maxim but I want to get the starting problem fixed before I do. I have rebuilt the carbs and I was hopeing that that would help but it didnt help at all. I have cleaned and gaped the plugs and I cant think of anything else it might be. After it finally starts it runs great. It has been this way since I bought it three years ago and i just put up with it, but now that it is time to sell it I want to fix it.

any ideas?

What's it sound like when you get on the starter?
Chug-chug-chug?
Whirrrr-thunk-chug?
Chug-pow-pow?

Check the choke to make sure the cable isn't sticking or frozen, and try connecting a car battery with jumper leads, then try the start operation again. If it fires right up, you can pretty much figure the battery needs to be replaced with one that has the right CCA-rating or higher (the battery may be weaker than the OEM one, downsized or just old).

Sorry, I should have elaborated...

Maybe this is just me and a I'm totally off...but when my plugs were fouled, they were hard to get started, but once they did, it did run... and I couldn't find anything else wrong in starting..

If you're not in the habit of running it regularly, it might be something as simple as the fuel in the carbs evaporating off their aeromatic compounds and being harder to start as a result. Does it act the same way if you get it to start and then shut it down 2 minutes later and try to repeat? If not, turn the petcock to PRIME for 60 seconds then back to ON before starting when she hasn't run in more than a day.

well i know from experience that unfouled plugs doe snto mean they are good. i had a terrible time getting my camaro timed. THe #1 cylinder would not spark unless at high rpm. This was with NEW spark plugs. I changed the sprark plug again with another in the same package and same issue. I ended up changin the wire with a known good cylinder. The dist cap. The dis rotor. and nothing. Finally i changed the plug again with a new pack and it wokred perfectly. So i have TWO bad spark plugs that were new in package.
