Dennis;

    William Magliocco has posted recently about a similar problem with his
'86 5kt - #2 is running rich and carboning up, other cyls are OK. He's
checked his compression and it's OK, he also installed new wires, cap, &
rotor. I think he's checking his fuel distribution system now - you may want
to get in touch  wmagliocco@sprintmail.com

It may be something similar to your problem.
