Newbie- idle funny

Newbie question but I just put a new carb Intake and new distrip on a 74 350 and after a buddy helped me install it all it was too dark to finish the idle setting and adjust the distrip, it fires up and will stay running but it idles really low then idles high for a bit them low again. My question is this a timing problem with the distrip not betting set right or the idle screws not set right?

I may be wrong but sounds like a vacuum issue
