new points, and a fouled plug question.

[jonzcustomshop]

1965 chevrolet 283 2bbl

first off the plugs, I pulled them and changed them last week, they were quite plugged up with carbon.. they were probably on there from before I got the truck.
plug #7 (lr drivers side) was fouled.-soaked in oil(?) and smelled of gas.
a couple of others also smelled strongly of gas.

the new plugs turned the 283 into a monster!
lots of power!
however the last couple of days it has started running rough again... I pulled #7 first, and it seems to be fouled out, smells of gas and dosen't seem to be firing.
pulled all the other plugs, and they all seemed like they were firing, dry spots on each, but they are all already starting to get dirty with carbon.

so, is there anything I can do about that # 7 cylinder?
what is wrong ?


next is the pionts.
I pulled them , and they are getting that peak/valley build up.
so I bought a new set, and have double checked that they are the correct ones, and installed them today. could not get the motor to fire.
I tried adjusting them up and down , but would not fire.
I put the old ones back in , and it fired right up.

did I get a bad set of points?
I was under the impression that i could put them in , and fire it up , and set the dwell with a dwell meter.
do I need to gap them first and then set the dwell?
or did I get a faulty set?
thanks.
