Tom,

Are you running too rich? The DZ doesn't run well rich...Its something about
raw fuel going in and putting out the fire. If the motor is running too rich
then it will shake like crazy and sound like its hammering and banging
around.....If you lean it out the motor will smooth out and be
awesome.....Needle valves vary but all the DZ's I have setup or seen run
seem to be at about (1) Turn open....In fact up here at elevation
5600-6000ft I'm only about 3/4 of a turn open...The motor is still "rich" of
the peak by about 200-300rpm and runs great....

You may look here for a solution rather than head shims.....I have never
heard of someone adding head shims to really solve a problem on this
motor...I have heard of people trying it and then they leaned the needle and
did not need it.

Troy
