My '89 Mighty Max 4 cyl 121 cid is blowing carbon from the exhaust pipe - black fine soot.
Any advice for troubleshooting or repair would be appreciated.

Sounds like it's running too rich (too much gas for the amount of air)This may be caused by a dirty aircleaner (limiting the amount of air and causing too rich a mixture).
There could be other reasons but start with the aircleaner.
