engine troubles

Engine troubles. I filled up with gas last week and the fuel truck was filling the tank, most times I try not to but I did. But no problems till today the first time since the fill up and at first no problems about 1 or 2 miles down the road and I think i m feeling a miss then. Once I stop I know its a miss pulled. Into another gas station and tried screwing with the timing and it stalled just by turning the dis. About 1/4" each way. So I got it running again got to work and when I left this morning I knew I wasn't. Going to run right so I started messing with the carb turning the air fuel screws and idle screw its running better just not right still feel the miss. Since its been about a year or two since the last tune up I'm going to do that today and suggestions if this don't work

Replace the filter I would like to think it ran a little better but I think its my mine playing tricks on me. Time for plugs

[Irish_Alley]

Well not sure what it was but its gone after replacing the plugs and tuning the carb again. Right after I changed the plugs it still didn't run right so I unplugged the pcv and the truck stalled, didn't rev up like it should so I tuned the timing and messed with the air fuel screws again now it seams to run right but while I'm at it I should change the cap and rotor

Couldn't leave well enough alone changed cap and rotor now no fire hot wire is hot changed out coils with one I had laying around. And the shaft is in before the grommet. Done for today got to get some sleep before work

I feel your pain. Mine was running fine too, the best it has been in fact, until I got some gas a couple weeks ago and now it's running all funny. Cleaned the filter, that gas is long gone, played with the distro, and I'm getting inconsistent behavior!

I changed plugs. Dint see nothing wrong any plugs still have a good gap.  But seamed to fix the problem also changed the filter?

[SUX2BU99]

Which plugs did you have and which do you have now?

Update LOL here we go. After swapping plugs I thought why not just change the cap and rotor. Well mistake it wouldn't get any fire. Checked and rechecked everything even chainged coils. Didn't know it but I had two bad coils so I got A new coil. Still no fire finally put old cap and rotor on and she fires right up. So I got a bad cap or rotor from autozone. But while I was messing with my cap and rotor I found a broken piece of plastic. It went to my Carb spacer, causing me to have a big vacuum leak and fuel leak that's what started my hole problem to begin with.
