I checked and noticed that there was a vacuum stem on the carb that had nothing connected to it.
I tried capping this stem, redid timing and now it kind of sputters under load and does not pull at all going uphill with some small poppy backfires. Again, once the vaccum advance kicks on it picks up speed and once up to speed it's ok. What should be plugged into this, or should it just be capped off? Does this sound more like a timing issue? Or maybe a carb issue?
All my vacuum lines are going to the right places as far as I know. PCV directly to manifold, transmission to lower inlet below carb, and distributor right above that which is ported.
Thanks guys!
