Make sure the dashpot it square to the plunger.  Also the plunger and dashpot should be cleaned with solvent on a rag and lightly coated with oil.  After cleaning and lite coat of oil, hold onto the carriage as you type the first CR as the plunger will likely not be aligned to the dashpot.

Also, there's a lever on the vent on the back of the dashpot that
controls how airtight it is.  Opening the vent too far allows the
carriage to slam to the left with a bang.  If the vent is closed
too far, the carriage will take too long to reach the left margin
and the first character you print may be smeared and not solidly
on the margin because it was printed while the carriage was in
motion.
