84 K10, Another Misfire?

After enjoying a couple weeks of no issues with my 84 K10, all of a sudden today it seems to be bogging out under load. Idle seems fine, I replaced the cap and rotor just for fun but there seems to be no difference. I'm going outside to check the fuel filter now (external) any other ideas what my issue could be?

I feel like I wanna blame it on fuel and not spark but I'm not sure enough to lean in that direction. I've got new plugs, wires, cap, and rotor.

Re: 84 K10, Another Misfire?

I took the fuel filter off and noticed that it seems like the previous owner put it on backwards. It says "IN" on the side going towards the carb and not the side coming from the fuel pump. I'm wondering if they're more susceptible to clogging if the flow is going the wrong way.....

I noticed on occasion it would backfire out the top of the carb when I'd force it to move trying to get it home from work yesterday.....
