FLAT TIP PUNCH f
Figure 22. Removing Distribution Pin
(20) Rotate the choke plate past the full open
position until it is nearly inverted. Place the
distribution pin in a section of brass tubing with the
end of the tube bearing against the choke shaft. Using
a flat tip punch or a piece of 1/8 inch drill rod, drive
the pin flush with the choke shaft. Then, using a
smaller diameter punch or drill rod, drive the pin out
of the choke shaft. Refer to "Special Tools and
Improvised Tools" on page 10 for complete
information on the improvised tools.
In the illustration (Figure 22), a section of the
upper portion of the brass tubing is shown
cutaway for the purpose of clarity. Do not cut
out this section of tubing.
