:confused:
As a new guy on the block and in working on BMWs i thought I'm pick the vast knowledge of this forum.
My 1991 318ic is fouling all plugs. I runs well otherwise. It's been sitting up for a while and I've put a new paint job on it and now i want to put it back on the road. Got any suggestions?

vast knowledge ? Ha ha.

Bad plugs: black dry deposits
running to rich
weak spark
inciorect timing

black oily crap: bad valve seals or rings

that what makes em not fire.

Also incorect gap will cause this too
