I think Wingnut is really close...

I think your carb is leaking fuel and flooding your engine when you stop. As a matter of fact its doing it all the time but when its running it is not causing you any problems, except for maybe slightly increased idle which you have probobly compensated for by readjusting it awhile back. When it sits over night the carb cools and your fuel has plenty of time to evaporate so it isn't doing it in the morning. the odd thing is because your engine starts good in the morning, your carb isn't odviously completely draining like the q-jet did on my 79 blazer when I lived in Alaska (ironicly) and had similar problems. I am not positive why your carb is leaking down from the info you provided so I won't b.s. you whith an answer. Enjoy Alaska and good luck with it... Pete.
