Bogged down While In Gear And Sputtered During Acceleration

BTW...isn't working on cars fun?
This was supposed to be a turn-key driver but instead turned into rolling restoration (money and time pit).
It was a gift from my wife so it's kind of a "gift horse" scenario. I do like working on it though. I've learned a ton of things forcibly by owning this one.

I'LL pull the timing cover and check the chain tomorrow. Thanks everyone for the insight and advice. I'll update in a couple days.
